type of RV or camper you ultimately pick will depend on how you plan to use it — your needs and wants. But you can’t (or at least shouldn’t) make that decision without knowing what’s available. So, that’s what we cover in this chapter. If you don’t have an RV or camper yet but you’re looking to get one, this is the chapter for you!
Motorhomes
You’ve seen them on the highway: giant motorhomes the length of a Greyhound bus with a sparkling paint job, the driver sitting up high in a big, comfy, padded chair behind a giant picture-window windshield. These are the Class As, and the moniker is easy to remember. But this is only one classification of motorhome. Motorhomes actually come in all kinds of sizes and configurations.
Motorhomes (sometimes called motor coaches) are extremely popular, partly because you don’t need a separate vehicle to tow them with. The simplest way to think of a motorhome is an engine and transmission mounted on a chassis, with a complete trailer plopped on top. Motorhomes can be powered by gasoline or diesel engines, and both engine types have their cheerleaders and detractors (see the nearby sidebar). (Some manufacturers are working on electric coaches, but they’re in the infant phase of development.)
One of the attractions of a motorhome is that passengers can get to everything easily while the vehicle is on the road. Safety experts agree that everybody should remain seated and belted in at all times when tooting down the highway, but the reality is that everybody (except the driver) can get up, move around, go to the bathroom, walk back and lie down in bed, raid the fridge, or watch a movie, all without stopping. That’s not the case with a towable trailer.
GASOLINE VERSUS DIESEL
In the RV world, the question of whether to buy a gasoline-powered motorhome or towing vehicle versus a diesel-powered one can sometimes enflame the sort of religious passions unseen since the Spanish Inquisition. Online discussions can quickly turn into battling revival meetings competing to save the souls of the undecided.
Most Class A rigs are powered by diesel, but some models have gasoline engines. With Class B and C, you have more choice. The same is true when you go shopping for a tow vehicle. Ford, Chevrolet/GMC, and RAM all offer a diesel option for their heavier-duty 0.75-ton and 1-ton consumer pickup trucks. We talk all about choosing towing vehicles in Chapter 7.
The pro-gasoline side has immediate economic savings in their favor. Gas-powered trucks and motorhomes are usually less expensive than diesels, often by a lot. And the price-per-gallon of gasoline is cheaper than diesel, too (at least as of this writing), and these beasts are mighty thirsty. Diesel fuel can be formulated differently, depending on the time of year and where you are in the country, because it’s a thicker, oilier type of fluid than gasoline. Get stuck with the wrong kind of diesel fuel when the temperature gets bitter cold, and it can turn into a gel, making it difficult to even start the engine. Many sources also recommend adding diesel exhaust fluid (DEF) every time you fill the tank to keep smoke from belching out of your exhaust pipe — so there’s another expense.
Diesel fuel also stinks worse than gasoline, and it seems to get all over everything sooner or later. That sounds like a whiny complaint, but there are folks who regard it as a deal breaker. You’ll undoubtedly step in a puddle of diesel fuel or get it on your clothes when you fill up. And you can’t always be positive that every gas station you come to has diesel. It’s less common when you get off the highway and take the scenic route. So motorhome RVers like to stick to truck stops, where diesel is always available (and where they have the room to maneuver their long rigs).
The biggest Class A motorhome diesel engines are usually on par with those found in commercial trucks. That means they’re much more expensive to maintain than gasoline engines. That quick-lube place on the corner isn’t going to give you its $19.95 oil change special for your Class A. The engine will have to be fixed and maintained by an RV dealer or a commercial truck service center. Because of the way diesel pushers are built, working on one often means the mechanics need to access the engine by going into your bedroom, bathroom, or closet and opening up the floor to reach components inaccessible from the outside. That adds time and expense. And no matter how long the shop needs to fix your RV, remember that you’ve just lost both your house and transportation until it’s fixed.
Now that we’ve talked you out of it, diesel has lots of advantages over gasoline, which is why most Class A motorhomes have diesel engines. Big Class As weigh a lot, even when they’re empty. And diesel engines generate more horsepower and torque, which means they can pull more weight more efficiently, especially when it comes to climbing hills. High-end Class As are packed full of heavy appliances, real porcelain toilets, granite countertops, custom wood cabinetry, and other weighty materials, even before you throw in your family and all their stuff and fill all the water tanks. A diesel engine is better at handling that massive load. (These same issues come into play when choosing a diesel truck for towing a heavy, loaded fifth-wheel trailer.)
Diesel also gets slightly better mileage per gallon than gasoline. With a big Class A coach, expect about 9 to 11 miles per gallon with a diesel engine, and closer to 7 to 9 miles per gallon with gasoline. Diesel engines cost more to buy, but they last much, much longer than their gas-powered counterparts. Diesel engines are designed for the long-distance, weight-hauling chores of commercial trucks.
Another consideration is that diesel Class A motorhomes often ride quieter on the inside because most are diesel pushers, with the engine mounted all the way in the back of the coach. Gasoline engines are usually up front, under the cockpit floor between the front seats.
Bottom line: If you intend on keeping your motorhome or tow vehicle for a long time and putting more than 100,000 miles on it, a diesel engine is the hands-down favorite. It also wins if you’re driving a heavier motorhome that’s towing a car or boat. But if you suspect you’ll only use your RV a few weeks a year and you plan on putting less than 10,000 miles on it annually, you can lean toward the savings of a gasoline engine.
When you pull out of your driveway in a motorhome, it carries everything, even electricity (most motorhomes have onboard electrical generators). When you compare sizes and prices with towable RVs, the sticker shock of motorhomes takes some getting used to, but remember, you’re self-propelled. You don’t have the additional expense of buying a $30,000 to $70,000 truck to haul it with. You also don’t have to tow anything behind you, although plenty of people do add a hitch to the back end to drag a car or even a boat. (You can find more about towing a car in Chapter 19.)
There are three basic classifications
