Best Class A Motorhomes: Gas, Diesel and Luxury Picks
The best class A motorhomes split cleanly on one decision — gas or diesel — because that choice sets your price band, your ride quality and your maintenance life more than any floorplan does. This shortlist picks six current models: two gas coaches, a family gas bunkhouse, the shortest sensible diesel, the volume luxury leader and the flagship at the top of the market, all from manufacturer specifications and published prices as of October 2026. Each pick states who it fits and what it costs you beyond money. For the class background — sizes, chassis and who Class A suits — see our Class A motorhome guide first.
How these picks were chosen
These are research-based selections from published specifications: chassis and engine, length, floorplan, tank and towing figures, and MSRP bands. They are not the product of hands-on testing, and no pick here is a reliability verdict — at this level, dealer quality and service history move ownership satisfaction as much as the badge does. Prices are typical asking ranges as of October 2026: new gas Class A motorhomes run $140,000–$300,000, diesel pushers $280,000–$650,000 or more, and flagships beyond $1,000,000.

Best budget gas Class A: Thor Motor Coach A.C.E. 29G
The A.C.E. line was designed as the crossover into Class A — compact at about 30.5 feet, with a king bed, a cab-over drop-down bunk and pet-friendly touches, on the Ford F-53 gas chassis that keeps purchase and service costs at the bottom of the class. At roughly $160,000–$190,000 as of October 2026 it undercuts most diesel anything by six figures. The 29G floorplan is also one of the few here designed around how couples actually travel with guests: the drop-down bunk carries visiting grandkids without converting the living space, and the outdoor kitchen and exterior entertainment options suit the campground-centric trips most A.C.E. owners take. Who it fits: first-time Class A buyers and trailer converts who want the bus-style driving position and basement storage without diesel money. The trade-off: entry-level fit and finish, more road and engine noise than any diesel, and a chassis working near its limits when loaded for a family.
Best gas family Class A: Forest River Georgetown 5 Series 36B5
The 36B5 is the family floorplan done properly at gas prices: mid-ship bunks, a bath-and-a-half, a rear king bedroom and sleeping for a large family without converting the dinette every night. At about 38 feet it is as big as gas Class A gets, and the 5 Series trim brings full-body paint and residential appliances. Who it fits: families who need bunkhouse sleeping and Class A space but cannot justify diesel. The trade-off: a petrol V8 moving a 38-foot, fully loaded coach will be slow on grades and thirsty everywhere — expect the fuel bill to remind you what you saved on the sticker. Expect $200,000–$235,000 as of October 2026.
Best gas Class A overall: Tiffin Open Road Allegro 36LA
If you have decided on gas, the Open Road Allegro is where the smart money stops: Tiffin's cabinetry, insulation and owner support applied to the same Ford chassis everyone else uses, in a 37-foot bath-and-a-half floorplan that has been a category benchmark for years. Resale values reflect the reputation. Who it fits: experienced owners who tour seriously but prefer gas running costs and Ford service access. The trade-off: at $240,000–$275,000 as of October 2026 it prices against entry diesel money used — the eternal Class A dilemma in one model. Our Tiffin motorhomes guide covers how the Open Road sits against Tiffin's diesel ranges.
Best first diesel pusher: Tiffin Allegro RED 33AA
The Allegro RED 33AA is the shortest route into diesel ownership: about 35 feet, a rear-engine Cummins on a Freightliner chassis with air suspension and air brakes, and Tiffin's interior standards, at roughly $350,000–$395,000 as of October 2026. The compact length keeps it usable in parks that exclude 43-footers, while the chassis delivers the quiet, torquey, long-life diesel experience. Who it fits: couples stepping up from gas who want the diesel chassis without the diesel footprint. The trade-off: tanks, storage and interior volume all trail the 40-foot coaches, and per-foot it is expensive — you are buying the drivetrain, not space.
Best luxury diesel: Newmar Dutch Star 4310
The Dutch Star is the volume luxury benchmark for a reason: a Spartan or Freightliner chassis with Newmar's Comfort Drive steering system, heated floors, full-tile showers, multiplex controls and build quality that full-timers cross-shop against coaches costing half again as much. The 4310's bath-and-a-half floorplan at about 43 feet is the range's sweet spot. Who it fits: full-timers and long-tour couples who will put serious miles and nights on the coach. The trade-off: $560,000–$660,000 as of October 2026, tag-axle complexity, and service that rewards planning — this is a machine to own deliberately, not casually.
Best flagship Class A: Newmar King Aire
At the top of the production market sits the King Aire: 45 feet on a Spartan K3 chassis with a 605-horsepower Cummins, interiors specified more like a custom residence than a motorhome, and a price from around $1,500,000 as of October 2026. Everything is bespoke-adjacent — floorplan finishes, technology, even the cockpit — and production is limited in a way that keeps used values firm. Who it fits: buyers for whom the coach is the destination. The trade-off: beyond price, it is the ownership ecosystem — specialist service, serious insurance and running costs, and a coach that demands to be used to justify itself. For context, our hub guide to RV prices puts flagship diesel coaches at $650,000–$1,000,000-plus; the King Aire is what "plus" looks like.
Gas vs diesel: the running-cost math behind the picks
The picks above split on purchase price, but ownership cost splits differently. A gas coach services at Ford truck rates almost anywhere in the country, burns cheaper fuel and returns perhaps 6–8 mpg doing it; a diesel pusher services at heavy-truck rates, wants diesel-specific maintenance on longer intervals, returns roughly 7–10 mpg, and is engineered for several hundred thousand miles of chassis life. Insurance, tyres and storage scale with the coach's value and footprint more than its fuel. The practical summary: a gas coach is cheaper to buy and cheaper per year, a diesel is cheaper per mile at high mileages and holds a higher share of its value — which is why the high-mileage full-timers on this list cluster in the diesel picks and the low-mileage family buyers in the gas ones. Run your own expected mileage through both columns before you let a sticker price decide for you.
How to choose among them
Decide fuel first, on miles rather than money: under roughly 8,000 miles a year, gas coaches deliver the same floorplans for far less purchase and maintenance cost; above that, diesel's ride, torque and service life start paying you back. Then decide length against your parks — the jump from 35 to 43 feet closes more campground doors than any other choice on this list. Finally, shop the used side before signing anything: three-to-five-year-old Dutch Stars, Allegro REDs and Open Roads list in depth on RV Frontier, and at Class A money the depreciation someone else absorbed is the largest single discount available anywhere in RVing.
