Just like diesel Class A RVs, gas-powered models are popular among retirees, remote workers, and families who want to travel without giving up the convenience of home.
Gas Class A RV Size & Space Advantages
Front-engine Class A gas models are typically shorter, lighter, and more maneuverable than the rear-engine “pusher” foundations of most Class A diesels. New “gassers” are predominantly built on Ford F-53 chassis with a 7.3-liter V-8 engine.
Gas-powered RVs range from 25.5 to 40 feet (7.8 to 12.2 meters) in length and typically fall between 30 and 36 ft (9.1 to 11 m). They weigh between 16,000 and 26,000 pounds (7,250 to 11,800 kilograms).
The distinctive, flat-faced Class A design isn’t very aerodynamic, but it does provide a huge, panoramic windshield with an amazing view of passing scenery. RV manufacturers such as Fleetwood, Thor Motor Coach, and Winnebago offer a wide variety of floor plans to suit couples, families, and groups. Most configurations include a primary bedroom with a king- or queen-size bed, a spacious galley, and generous living areas and seating.
How Gas Class A Motorhomes Compare To Diesel Class A Motorhomes
Compared with a diesel Class A motorhome, a gasser may have advantages in:
- Lower purchase price
- Simpler, cheaper maintenance with no diesel exhaust fluid (DEF) to refill and no water separator to service
- Bigger selection with more gas motorhomes for sale
- Lower engine noise than a diesel at low speeds and idle (although the opposite is true at highway speeds because gasoline engines are mounted in front)
Gas vs. Diesel Class A RV Towing Capacity
Gas-powered Class A motorcoaches have respectable towing capacities, but they can’t compete with the pulling torque of larger diesel units:
- Gas-powered Class A RVs - 5,000 to 8,000 lbs (2,270 to 3,630 kg)
- Diesel Class A RVs - 5,000 to 20,000 lbs (9,070 kg)
Still, in most cases, a gas-engine coach can pull an average car (affectionately called a “toad,” a play on “towed car”), or a small truck or SUV. However, if you plan to head into the mountains while towing a 4x4 or boat, you should strongly consider a diesel Class A RV instead.
What To Consider When Buying A Class A Gas RV
Here are a few additional things to keep in mind when thinking about buying a Class A motorhome:
- Expense - Class A motorhomes are among the most expensive RVs to purchase, insure, refuel, and maintain—but gas Class As cost less than diesels.
- Fuel economy - Gasoline coaches only get about 6 to 10 miles (9.7 to 16 kilometers) per gallon, lagging behind diesel models’ 8 to 14 mpg (13 to 22.5 km/g). On the other hand, diesel fuel usually costs about 15% more.
- Parking and camping - This type of RV’s large size can limit access to certain campgrounds, national parks, and neighborhoods.
- Driving - Driving and parking a vehicle of this size requires skill and practice, and in some states a special license, so check the states where you plan to travel before driving.
- Power and torque - Diesel pushers tend to perform better on hills than gas-engine models, especially while towing.
- Ride quality and handling - Gas RVs’ springs and hydraulic brakes are easier to maintain, but the air suspensions and air brakes in Class A diesels ride and handle better
