Quick Answer: Jayco has the edge for buyers who prioritize a longer warranty, heavier-duty construction features, and access to both towable RVs and motorhomes. Keystone often wins on entry-level price and offers strong travel trailer, fifth wheel, and destination trailer options. At the mid-range and luxury levels, the better choice usually comes down to the specific floor plan, price, and condition of the RV. If you have narrowed your search down to Jayco vs Keystone, you have already done the hard part. Both are among the best selling names in travel trailers and fifth wheels, both are owned by the same parent company, and both show up constantly in the same dealer lots and owner forums. So what actually separates them? The answer comes down to construction details, warranty length, and which specific model line you are cross shopping, not just brand loyalty.This guide breaks down how Jayco and Keystone are built, what their warranties really cover, how their most popular models stack up on price, and what owners say once the new camper smell wears off.Key TakeawaysJayco and Keystone are both owned by Thor Industries, but they maintain separate factories, engineering teams, and product lineups.Jayco offers a 2-year limited base warranty and 3-year structural coverage, while Keystone generally offers a 1-year base warranty and 3-year structural coverage.Jayco tends to include heavier-duty construction features more consistently across its lineup, including its Magnum Truss roof and Stronghold VBL wall construction.Keystone often has the lower entry price, particularly with models such as the Bullet and Hideout.Jayco builds Class A, Class B, and Class C motorhomes in addition to towables, while Keystone focuses entirely on towable RVs.In mid-range and luxury fifth wheels, comparisons like Eagle vs. Cougar and Pinnacle vs. Montana often come down more to floor plan and individual unit condition than brand alone.Regardless of which brand you choose, a pre-purchase inspection is especially important when buying used because condition can matter more than the badge on the RV.Same Parent Company, Different PlaybooksA lot of shoppers do not realize that Jayco and Keystone are both owned by Thor Industries. Thor bought Keystone in 2001 for around $145 million, then acquired Jayco 15 years later in 2016.Despite sharing the same parent company, the two brands still operate very differently.Jayco: The Older, More Established BrandJayco was founded in 1968 by Lloyd and Bertha Bontrager in Middlebury, Indiana. Over the decades, it grew into one of the biggest names in RV manufacturing, with the Jay Flight becoming the top-selling travel trailer line in the country.Jayco has kept its own factories, engineering teams, construction methods, and product philosophy under Thor ownership.Keystone: A Faster-Rising CompetitorKeystone was founded much later, in 1996, by Coleman Davis in Goshen, Indiana. The company grew quickly and became one of the fastest-growing RV manufacturers in the country before Thor acquired it just five years later.Like Jayco, Keystone still operates with its own manufacturing and engineering approach rather than functioning as a renamed version of another Thor brand.What They Have in CommonEven though their histories and product strategies differ, Jayco and Keystone share a few important things:Both are owned by Thor Industries.Both manufacture RVs in northern Indiana.Both compete heavily in travel trailers and fifth wheels.Both have their own factories, engineering teams, and model lineups.Both are widely available through major RV dealers.Northern Indiana remains the center of gravity for both brands, which is why the region is often compared to Detroit for the RV industry.Interested in more RV Brands?

Both brands have upgraded their construction over the years, but they take slightly different approaches to walls, roofs, floors, frames, and slide-outs.Jayco: Heavier-Duty Features Across More of the LineupJayco builds most of its towables around its Stronghold VBL construction. Sidewalls, rear walls, and slide-out walls are vacuum bonded under roughly 144 tons of pressure for at least 16 minutes, combining welded aluminum framing with a fiberglass exterior.Jayco also uses its Magnum Truss roof system, rated to hold up to 4,500 pounds. Floors on most models use 5/8-inch tongue-and-groove plywood rather than the OSB-style board found in some competing RVs.Some of Jayco's standout construction features include:Stronghold VBL vacuum-bonded wallsWelded aluminum framingMagnum Truss roof rated to 4,500 pounds5/8-inch tongue-and-groove plywood flooringCustom-built frames with integrated A-framesSlide-outs engineered around individual floor plansKeystone: More Aluminum and Modernized ConstructionKeystone has moved closer to Jayco's construction approach in recent years, particularly across its newer and higher-end lines.Current Keystone travel trailers and fifth wheels use features such as a five-sided aluminum superstructure, laminated sidewalls, structural I-beam frames with stamped steel cross members, and Keystone's proprietary Tru-Fit slide-out system.Newer models such as the Walkabout also move further away from traditional wood construction by using more aluminum panel components.Jayco vs. Keystone Construction at a GlanceBoth brands now use modern construction methods, but the details still differ:Wall construction: Jayco uses Stronghold VBL vacuum-bonded, aluminum-framed walls on most models. Keystone uses laminated walls with a five-sided aluminum superstructure on current lines.Roof system: Jayco's Magnum Truss roof is rated to hold up to 4,500 pounds. Keystone's roof construction varies more by model and product line.Floor material: Jayco uses 5/8-inch tongue-and-groove plywood across much of its lineup. Keystone uses a mix of plywood and OSB depending on the model.Frame: Jayco uses custom-built frames with integrated A-frames on towables. Keystone uses structural I-beam frames with stamped steel cross members and outriggers.Slide-outs: Jayco engineers slide systems around individual floor plans, while Keystone uses its proprietary Tru-Fit slide construction across much of its current lineup.Which Brand Has the Construction Edge?The gap is smaller than it once was. Both manufacturers have invested heavily in stronger materials and more modern construction.Jayco still tends to have the advantage when it comes to including heavier-duty construction features across more of its lineup, including entry-level models. Keystone increasingly matches those approaches, particularly in newer and premium product lines.Warranty Coverage: Jayco's Extra YearWarranty length is one of the clearest differences between Jayco and Keystone, and it is one of the easiest areas to compare directly.Jayco: Longer Base CoverageJayco backs its towable and motorized RVs with a 2-year limited base warranty plus 3 years of structural coverage, commonly marketed as its 2+3 warranty.That means Jayco gives buyers twice as much base warranty coverage as Keystone on most models.Keystone: Shorter Base Warranty, With One Big ExceptionKeystone's standard coverage is a 1-year limited base warranty plus a 3-year limited structural warranty.There is one important exception: Montana and Montana High Country models built after January 1, 2026, receive 5 years of structural coverage. That brings Keystone much closer to Jayco on paper for buyers shopping those specific fifth wheel lines.Jayco vs. Keystone Warranty CoverageHere is the side-by-side comparison:Jayco base warranty: 2 years for defects in materials and workmanship.Jayco structural warranty: 3 years for major structural components such as the frame, walls, and roof.Keystone base warranty: 1 year for defects in materials and workmanship.Keystone structural warranty: 3 years on most models.Montana and Montana High Country: 5 years of structural coverage on models built after January 1, 2026.Transferability: Structural warranties from both brands can transfer to a second owner within the original coverage period.What About Warranty Claims?Both companies handle claims in a broadly similar way. During the first year of ownership, the manufacturer typically administers supplier and component warranties rather than forcing owners to chase multiple parts manufacturers themselves.Which Brand Has the Warranty Edge?Jayco has the clearer advantage overall because of its 2-year base warranty.Keystone narrows that gap considerably with the 5-year structural warranty on newer Montana and Montana High Country models, but for most buyers comparing the brands across their full lineups, Jayco still provides longer standard coverage.Comparing the Model Lines Buyers Cross-Shop MostComparing Jayco and Keystone as whole brands only gets you so far. Both build everything from lightweight entry-level trailers to large luxury fifth wheels, and the better choice can change completely depending on which two model lines you put side by side.The easiest way to compare them is by market segment.Entry-level travel trailers: Jay Flight SLX from Jayco; Hideout and Bullet Classic from Keystone.Lightweight travel trailers: Jay Feather Air and Jay Feather from Jayco; Passport and Bullet Crossfire from Keystone.Premium travel trailers: Eagle HT from Jayco; Cougar Half-Ton from Keystone.Entry/mid-range fifth wheels: Eagle SLE and Eagle HT from Jayco; Cougar Sport and Cougar Half-Ton from Keystone.Premium fifth wheels: Eagle from Jayco; Cougar and Arcadia from Keystone.Luxury fifth wheels: North Point and Pinnacle from Jayco; Montana High Country and Montana from Keystone.Toy haulers: Seismic from Jayco; Carbon and Raptor from Keystone.Destination trailers: Jay Flight Bungalow from Jayco; Retreat from Keystone.Motorhomes: Redhawk, Greyhawk, Seneca, Alante, Precept and more from Jayco; Keystone does not offer motorhomes.That wider view immediately shows one of the biggest differences between the brands: Keystone has a particularly deep towable lineup, while Jayco stretches into virtually every major RV category, including Class A, Class B, and Class C motorhomes.Entry-Level Travel Trailers: Jay Flight SLX vs. Hideout and Bullet ClassicThis is where first-time buyers are most likely to start.Jayco's Jay Flight family has been America's best-selling travel trailer for more than 20 years, according to Jayco. For 2026, the Jay Flight SLX starts at $17,318 and ranges from tiny single-axle models to large family bunkhouses. The 250BH sleeps up to eight, the 284BHSW sleeps up to 10, and the 325BHT stretches that to 11.Keystone counters with Hideout and Bullet Classic. Hideout spans 17 floor plans, including the 230BH and 262BHS bunkhouses, both rated to sleep eight. Bullet Classic covers an even broader weight range, with some models under 3,000 pounds and bunkhouse layouts such as the 26BHC sleeping eight.For buyers in this segment:Choose Jay Flight SLX if you want a huge selection of family layouts, strong brand recognition, and unusually high sleeping capacities in the larger bunkhouses.Look closely at Hideout if you want straightforward conventional travel trailers with lots of floor-plan choice.Consider Bullet Classic if lower weight and easier towing matter as much as interior space.This is also where Keystone can be particularly aggressive on value, while Jayco's selling point is often how many of its construction and family-oriented features trickle down into less expensive models.Lightweight Travel Trailers: Jay Feather vs. Passport and BulletMove up from the entry-level segment and the comparison becomes Jay Feather and Jay Feather Air against Keystone Passport and the broader Bullet family.Jay Feather Air is the lighter Jayco option, with 2026 models ranging from 3,630 to 4,505 pounds and sleeping up to eight. The full Jay Feather range expands considerably, topping out at 10 sleepers. The 29QBH is a good example of what Jayco can do with the format: it sleeps up to 10 while retaining the lighter, more towable positioning of the Jay Feather line.Keystone's Passport Super Lite is the natural cross-shop. Current models span roughly 5,260 to 8,530 pounds with capacities up to 10 people. The 2220BH and 229BH both sleep eight. Bullet Crossfire also targets buyers looking for smaller, lighter trailers without dropping all the way to bare-bones entry-level equipment.For SUV and half-ton truck owners, this may be the most important comparison in the entire lineup. Payload, hitch weight, and loaded trailer weight can narrow your options faster than brand preference.Premium Travel Trailers: Eagle HT vs. Cougar Half-TonBuyers wanting something more substantial than a lightweight trailer without moving into a fifth wheel should look at Jayco Eagle HT and Keystone Cougar Half-Ton travel trailers.The Eagle HT moves Jayco toward a more residential feel, with features such as Climate Shield weather protection, larger holding capacities, taller interiors, and upgraded sleeping and kitchen equipment. The 2026 line starts at $45,375.Keystone's Cougar family covers a similar buyer but gives shoppers several paths, including Cougar Half-Ton travel trailers as well as fifth wheels. That makes Cougar one of Keystone's most useful model families for buyers who want to stay in the same product line while changing RV types later.At this level, price stops being the only question. Four-season capability, tank capacity, slide design, bed size, storage, and the exact towing numbers become much more important.Lighter Fifth Wheels: Eagle SLE and Eagle HT vs. Cougar Sport and Cougar Half-TonThe fifth-wheel comparison deserves more nuance than simply "Eagle vs. Cougar."Jayco now has Eagle SLE and Eagle HT below the full-size Eagle. The 2026 Eagle SLE includes the 28BHU bunkhouse, which sleeps up to eight, while Eagle HT includes models such as the 29DDB and 31QCD for buyers who need more sleeping space. Eagle HT starts at $53,250, with models between roughly 8,120 and 9,835 pounds unloaded.Keystone answers with Cougar Sport and Cougar Half-Ton. Cougar Sport starts in the mid-$40,000s and weighs roughly 7,080 to 7,800 pounds, while Cougar Half-Ton expands the range to seven floor plans weighing roughly 7,864 to 9,590 pounds. Both can accommodate up to 10 people in selected layouts.That makes these some of the most direct fifth-wheel comparisons in the lineup:Eagle SLE vs. Cougar Sport for buyers entering fifth-wheel ownership.Eagle HT vs. Cougar Half-Ton for buyers wanting more equipment and floor-plan variety without immediately jumping to a full-size luxury fifth wheel.Do not take "half-ton" branding as permission to skip the numbers. Payload and pin weight still need to be checked against the specific truck and floor plan.Premium Fifth Wheels: Eagle vs. Cougar and ArcadiaFull-size Jayco Eagle moves into much more substantial fifth-wheel territory. The 2026 lineup includes floor plans such as the 355MBQS, which sleeps up to eight, and the 360DBOK, which uses an unusual double-upper-bunk-over-queen arrangement. Current Eagle fifth wheels start at $75,375.Keystone gives buyers two meaningful alternatives here.Cougar Premium is the more obvious Eagle competitor. Its nine current floor plans range from roughly 9,674 to 12,499 pounds and can sleep as many as 10 people. The 360MBI is particularly family-friendly, combining a bonus room, loft, island kitchen, and sleeping capacity for 10.Arcadia takes a slightly different approach. It emphasizes taller ceilings, larger storage areas, and three-quarter-ton towability, with current full-size models stretching past 40 feet. Floor plans such as the 3850RK even add features such as a mud room, washer/dryer space, and half bath.This is the point where floor plan matters far more than the badge. An Eagle 355MBQS and Cougar 360MBI can suit a family very differently from an Arcadia rear-office layout even when all three occupy a similar premium fifth-wheel market.Luxury Fifth Wheels: North Point and Pinnacle vs. Montana High Country and MontanaAt the luxury end, Jayco actually gives buyers two steps.North Point sits below Pinnacle but is already firmly in luxury territory. The 2026 range starts at $117,600 and includes family-oriented floor plans such as the 377RLBH, which sleeps up to nine, and the 390CKDS, which sleeps up to seven and carries 137 gallons of gray-water capacity.Pinnacle is Jayco's flagship fifth wheel. Current models use 102-inch wide-body construction and heavy steel framing, with floor plans stretching past 44 feet. The 39FLOK sleeps up to six, while the 38FBRK provides a bath-and-a-half layout aimed more at couples and extended-stay buyers than large families.A 2025 Jayco Pinnacle 38FBRK on Pop Sells provides a useful real-world example of the type of unit buyers encounter on the market.Keystone counters with Montana High Country and Montana. High Country occupies the lighter side of the luxury segment but still stretches to nearly 44 feet, with floor plans sleeping up to 10. It also now carries a 5-year structural warranty on qualifying newer models. Montana sits at the top of Keystone's conventional fifth-wheel range.Pop Sells' 2021 Keystone Montana High Country 377FL also shows why used luxury fifth wheels deserve attention. Buyers can often step into a much more elaborate floor plan by letting the first owner absorb the steepest early depreciation.Toy Haulers: Seismic vs. Raptor and CarbonIf the garage matters as much as the living room, the comparison changes again.Jayco's Seismic range includes both travel-trailer and fifth-wheel toy haulers. The fifth-wheel Seismic 399 stretches to 46 feet 9 inches, carries a 13-foot 6-inch garage, sleeps up to eight, and has a GVWR of 20,400 pounds.Keystone counters with Raptor and Carbon. Raptor occupies the more premium side of the family, while Carbon provides a more accessible route into large-garage toy haulers. Keystone currently offers both fifth-wheel and travel-trailer configurations, including lighter Carbon aluminum-sidewall models that sleep six.Here the decision should be driven by garage dimensions, cargo capacity, fuel capacity, sleeping arrangement, and tow vehicle rather than simply which interior looks better at a dealer.Destination Trailers: Jay Flight Bungalow vs. RetreatKeystone does not have the destination-trailer category to itself.Jayco's 2026 Jay Flight Bungalow is specifically designed for longer stays, with six layouts reaching roughly 42 feet. Loft models such as the 401LOFT DS sleep up to eight, while the JayLoft sleeps up to nine. Residential refrigerators, tall interiors, larger kitchens, and loft sleeping areas push these much closer to a small seasonal home than a conventional weekend travel trailer.Keystone's Retreat targets the same basic buyer: someone setting up for a season at a campground, lake property, or warm-weather destination rather than hitching and moving every few days.A 2023 Keystone Retreat 391LOFT on Pop Sells is a good example of the lofted, residential-style layouts buyers can find on the used market.For these buyers, towing manners matter much less than interior height, residential appliances, loft space, climate control, storage, and how well the RV works once it stays parked for weeks or months.Motorhomes: A Category Keystone Cannot MatchThis is the biggest structural difference between Jayco and Keystone.Keystone is a towable-RV manufacturer. Jayco also builds Class A, Class B, and Class C motorhomes, which means a buyer can move from a Jay Flight trailer into a Greyhawk, Seneca, Alante, or Precept without leaving the Jayco brand.For families, Redhawk and Greyhawk are particularly relevant. The 2026 Redhawk offers four floor plans and sleeps up to seven, while Greyhawk is Jayco's more heavily equipped gas Class C and also sleeps up to seven.The Redhawk 31F is a good example, combining a Ford E-450 chassis with sleeping capacity for seven. Pop Sells also has a 2025 Jayco Greyhawk 30Z, giving shoppers a real-world Class C comparison alongside Jayco and Keystone towables.If you are deciding between a motorhome and trailer rather than simply between two towables, our guide to diesel vs. gas RVs can help narrow down which type of motorized RV makes sense.So, Which Model Line Is the Better Buy?There is no single Jayco-vs.-Keystone winner across every price point.Choose Jay Flight SLX, Hideout, or Bullet Classic if affordability and straightforward family camping come first.Look at Jay Feather, Passport, and Bullet if lower towing weight is a priority.Compare Eagle SLE/Eagle HT against Cougar Sport/Cougar Half-Ton when stepping into your first fifth wheel.Put Eagle, Cougar, and Arcadia side by side if you want a premium fifth wheel without jumping straight to flagship pricing.Compare North Point and Pinnacle with Montana High Country and Montana for luxury or extended-stay use.Cross-shop Seismic with Raptor and Carbon if you need a toy hauler.Compare Jay Flight Bungalow with Retreat for seasonal or semi-permanent camping.Choose Jayco by default if you want a motorhome, since Keystone does not build one.At almost every towable price point, the smartest comparison is model against model, and often floor plan against floor plan. That tells you far more than simply deciding that one badge is "better" than the other.Learn more about the best RV brands for families. What Real Owners SayOwner forums give you a useful look at what Jayco and Keystone RVs are like after the dealer walkthrough is over. While every RV needs maintenance, plenty of owners in these discussions report years of enjoyable use, solid reliability, and relatively minor issues.Jayco Owners: Plenty of Long-Term Success StoriesIn a Reddit discussion about Jayco travel trailers, several owners praised their trailers for comfort, durability, and long-term reliability.One owner living full time in a Jayco Hummingbird reported:"Very warm and comfortable. Never a leak, never a rodent... Not one issue! Love it!!"Another owner described an older Jayco Eagle as "so well made despite being old," adding that they had "no issues with it whatsoever" and considered it a great first camper. Another Jayco owner simply summed up the experience with: "We love ours. Been a great trailer so far."The positive feedback continues in a separate discussion about Jayco quality. One commenter with RV-industry experience said:"You have much higher odds of getting a good unit from Jayco than most manufacturers."Another owner reported only one minor issue with a Jayco travel trailer and no problems with a 2017 Jayco Class C, adding that Jayco would be the first brand they checked when it was time to buy again.Keystone Owners: Lots of Happy Campers TooKeystone also gets plenty of positive owner feedback across several of its best-known model lines.In a discussion about Keystone RVs, one Hideout owner wrote:"We love our trailer. No issues. Just stay on top of maintenance."Another owner said they "absolutely love" their 2021 Keystone, use it frequently, and would recommend it to other buyers. A Keystone Sprinter owner also reported a very positive experience, with no meaningful problems beyond issues they caused themselves.Cougar owners had good things to say as well. One owner of a Cougar 28RKS fifth wheel said:"We love it. No notable problems outside of standard maintenance."That is especially relevant for shoppers comparing Keystone Cougar against Jayco Eagle, since both are popular choices in the mid-range fifth-wheel market.Keystone Owners Report Strong Long-Term UseThe Is Thor/Keystone Really That Bad? discussion includes several owners pushing back against the idea that Thor-owned RVs should automatically be avoided.One Montana owner reported:"Love it and have had very limited issues but nothing that required more than tightening a screw or two."Another owner had lived in a 2018 Keystone Sprinter with their spouse for almost three years. After a couple of minor warranty repairs early on, they said the RV had otherwise "been great."One full-time owner had also put around 5,000 miles on a Keystone without RV-related problems and described the unit as having "good bones."The Bigger Picture From OwnersThe strongest pattern across these threads is that both Jayco and Keystone have plenty of satisfied owners who have camped, traveled, and even lived full time in their RVs for years.A few themes come up repeatedly:Jayco owners often praise build quality, comfort, and long-term reliability.Keystone owners report strong experiences across Hideout, Sprinter, Cougar, and Montana models.Many owners describe problems, when they do occur, as minor maintenance or warranty items rather than deal-breakers.Routine maintenance plays a major role in how well any RV holds up over time.Buying a well-maintained individual unit can matter just as much as choosing between the two brands.For shoppers, that is encouraging. Both Jayco and Keystone have a large owner base, proven model lines, and plenty of examples of RVs delivering years of successful travel. A pre-purchase inspection is still smart, especially on a used RV, but there is no shortage of positive real-world ownership experiences on either side.Resale Value and Long-Term CostJay Flight's long running status as the best selling travel trailer in America tends to help resale value simply because of demand and parts availability. Used Jay Flights, Eagles, and Pinnacles are easy to find and easy to sell later because so many are on the road. Keystone's Cougar, Montana, and Bullet lines carry similarly strong resale numbers thanks to comparable production volume, though buyers should expect slightly softer pricing on Keystone's true entry level trailers compared to Jayco's equivalents.For either brand, the same rule of thumb applies: fifth wheels and travel trailers depreciate fastest in the first three to five years, then level off, which is exactly why used units in that age range, like the 2021 Montana and 2023 Retreat listed above, often represent the best value per dollar.Which Brand Fits Your Camping StyleIf you tow with a half ton truck and want the widest selection of dealers and floor plans, Jayco's Jay Flight and Eagle lines give you more inventory to choose from nationwide. If your top priority is the lowest sticker price on an entry level trailer, Keystone's Bullet and Hideout lines usually come in a bit cheaper. If you are shopping the luxury fifth wheel segment, the Pinnacle and Montana are close enough in construction and features that the deciding factor often comes down to floor plan preference and which specific unit is available near you. And if a motorhome is even a remote possibility down the road, that is a Jayco only conversation since Keystone does not build one.Choose Jayco if: you want the longer 2 plus 3 warranty, the widest dealer network, or you might want a motorhome someday.Choose Keystone if: your top priority is the lowest entry level price or you want a destination trailer for extended stays.Either brand works well if: you are shopping mid-range to luxury fifth wheels, since Eagle vs Cougar and Pinnacle vs Montana come down to floor plan more than brand.Do this regardless of brand: get a pre-purchase inspection on any used unit, since individual condition matters more than badge once an RV is a few years old.Find Your Next Jayco or KeystoneWhether you land on a Jay Flight, a Pinnacle, a Montana, or a Greyhawk, the best next step is comparing real listings rather than spec sheets alone. Browse current fifth wheels and travel trailers on Pop Sells to see what is actually available near you right now, and reach out directly through any listing with questions about a specific unit.Frequently Asked QuestionsIs Jayco or Keystone Better Quality?Both brands have improved construction significantly in recent years, and both are owned by Thor Industries. Jayco tends to include heavier-duty features like its Magnum Truss roof and Stronghold VBL walls more consistently across its lineup, while Keystone has closed some of that gap with aluminum-framed construction on newer models. Individual unit quality still varies more than brand reputation alone would suggest.Why Does Jayco Have a Longer Warranty Than Keystone?Jayco has marketed its 2-year base warranty as an industry-leading differentiator since 2020, while Keystone's standard base warranty remains 1 year. Both brands offer 3-year structural warranties, though Keystone recently extended that to 5 years on newer Montana models.Does Keystone Make Motorhomes?No. Keystone builds only towable RVs, including travel trailers, fifth wheels, destination trailers, and toy haulers. Jayco builds both towables and a full motorized lineup across Class A, Class B, and Class C motorhomes in gas and diesel configurations.Which Is Cheaper, Jayco or Keystone?At the entry level, Keystone's Bullet and Hideout trailers typically list a bit lower than Jayco's Jay Flight. Moving up into fifth wheels, pricing between the Eagle and Cougar lines, and between the Pinnacle and Montana, tends to land in a similar range depending on floor plan and options.
