(This post is part of a series. If you’re new to my blog or this is the first you’ve seen of this series, you might look at the introduction first.)
I live in an RV, but just what does that mean? “RV” is actually an abbreviation for Recreational Vehicle, although many of us who live in one full-time prefer to think it really stands for Residence or Residential Vehicle. Elsewhere in the world “recreational vehicle” refers to the ruggedized, often four-wheel drive vehicle that we call an SUV, or Sport Utility Vehicle, but here in North America, an RV is a motor vehicle or trailer having at least the basic necessary amenities of a home. For licensing, registration, and insurance purposes, to qualify as an RV a unit must include, at minimum, sleeping, cooking, and toilet facilities. In most other parts of the world a similar unit would be called either a camper van, if motorized, or a caravan, if towed. It is self-contained and self-sufficient, enabling all on-board systems to be functional without external connections for periods of days, weeks, or even months.
Now that we’ve defined the umbrella term RV, let’s take a look at all the different types of RVs. We can start by separating the lot into two groups: drivable and towable.
Drivable RVs are called motorhomes. They have an engine, a steering wheel, and a driver’s seat. They are fully self-contained motor vehicles that are also fully functional residences. Or, as Homer Simpson says, “It’s not just a motorhome — it’s a car you can go to the bathroom in!” They have the advantage of being a single vehicle that does it all. The disadvantage is that most motorhomes are too cumbersome and fuel inefficient to use as daily drivers. Most motorhome dwellers either tow a small car behind the motorhome or carry a bicycle, scooter, or small motorcycle for everyday local transportation.
Class A motorhomes are the largest of the motorhomes, built on a truck or bus chassis. They resemble a bus in that they usually have a flat front and boxy shape to them. The driver’s seat is obviously located at the front of the cabin, but there is no separate cab.
Bus conversions are a subset of class A motorhomes. A transit or school bus is converted, either commercially or DIY, into a custom motorhome. Commercially manufactured bus conversions usually start with a new empty bus shell, while DIY conversions are often made from retired commercial or school buses. There is plenty of room for creativity and originality in DIY conversions – many are as much works of art as they are homes on wheels.
Class B motorhomes are built inside a modified standard full-size van, and are sometimes called camper vans. From the outside it might be difficult to tell a class B motorhome from a regular van – the exterior differences include a raised roof (so that one may comfortably stand erect inside) and various vents and connections belonging to appliances and subsystems but may go unnoticed to the untrained eye. One of the biggest advantages of the class B van is that it is small and nimble enough for regular driving, so it could easily be your only vehicle. It’s also pretty stealthy, working well for urban camping.
Class C motorhomes are built upon a “cutaway” van or truck chassis. They retain the truck chassis’ cab, complete with its doors, windows, dashboard, and driver’s seat and controls. From the outside they are easily recognized by the telltale “cab over” portion of the coach which overhangs the cab.
Towable RVs — trailers — have the advantage of being able to un-hitch and use the tow vehicle for local transportation without having to carry your whole house around as you would with a motorhome. Trailers also come in a variety of styles.
Travel trailers are perhaps the most common trailers. They are towed by a bumper- or frame-mounted ball type hitch. They are sometimes also called bumper-pull trailers. For all but the smallest and lightest travel trailers, you’ll need a full-size pickup truck or large SUV to tow it with.
Other bumper-pull trailers include popups, sometimes called tent trailers, which are low profile when closed for travel, but “pop up” into a soft sided tent-like structure for camping, as well as “teardrop” and other hard-sided micro trailers. The advantage to these lightweight trailers is that they can be easily towed by almost any vehicle, including a compact car or mini pickup.
Fifth-wheel trailers connect to the tow vehicle using a fifth-wheel hitch and kingpin system, just like a semi-trailer on a big truck. The fifth-wheel hitch is installed in the bed of a pickup truck, though some owners of very large fifth-wheel trailers prefer to use a semi tractor instead of a pickup truck as a tow vehicle. The big advantage of a fifth wheel trailer is size and carrying capacity. If you want the most living space possible and less risk of overloading it, a fifth wheel would be a good choice. In addition to the extra towing capacity, a fifth wheel offers improved handling and maneuverability over a travel trailer’s bumper pull system.
There’s one more type of RV that’s worthy of mention but is neither motorized nor towable. The pickup camper is a complete dwelling unit that slides into the bed of a pickup truck. This combination offers some of the convenience of a tiny motorhome with some of the advantages of a trailer. At the campsite, the camper can be supported by jacks and the pickup truck can be driven out from under it, so it may be driven as needed without having to break camp.
That’s Not An RV!
The Mobile Home – while it is a house on wheels, it is usually mobile in name only. They are difficult to move, and therefore it is rarely done. Also, they are not fully self-contained – they need to be connected to water, waste, and electric infrastructure. House Trailer is another name for a mobile home.
Did I miss something? Have any questions? Comments are open!
Think you covered it all.
I like the term “Draggable Domiciles”.
Thanks, Betty! It’s a challenge sometimes to inject a bit of humor into an otherwise dry topic like this. I’m glad you liked it.
Mike — I didn’t comment on this post because I didn’t get it by email. Something must have gone wrong. I’ll watch your site and my email and make sure I get the next one.
I appreciate the definitions so we’re all on the same page. And as you know, I’m very much looking forward to the rest of this series.
I dunno, Gip — could it have gotten caught in your spam filter? Or maybe you got somehow unsubscribed.
I’m looking forward to getting into the more interesting material myself.
Decades ago I remember seeing a flying RV on the cover of Popular Mechanics or Popular Science. It was a large troop carrier sized helicopter retrofitted as a home that flies. Now THAT would be way cool. I’d almost trade my flying car for one of those.
And how about the various marine RVs that many people live on, yachts, houseboats, pontoons etc?
Oh, yes. While a boat can be much larger, since it doesn’t have to fit and be maneuverable on the roads, many are about the same size as RVs, and present the inhabitant many of the same challenges, as well as ons unique to the marine environment.
