RVs come in many shapes and sizes, but there are basically two types, motorized and towable.
MOTORIZED
Motorhome (MH) – A motor vehicle built on a truck or bus chassis and designed to serve as self-contained living quarters for recreational travel.
There are three classes of motorhomes: Class A, Class B and Class C.
Class A
Often resembling a bus, Class A motorhomes have a flat front end with large side windows. They may also be equipped with slideouts.
Class B
Also known as a campervan, Class B motorhomes tend to look like conventional vans, usually with a raised roof.
Class C
This RV type combines a van cab front with an RV shell. Many models typically have over-the-cab sleeping areas.
TOWABLE
5th Wheel (FW)
A trailer and hitch configuration connected to the tow truck directly above the rear axle by way of a special fifth wheel hitch. This causes several feet of the connected trailer to hang over the tow truck.
Travel Trailer (TT)
Also referred to as bumper pulls, these types of rigs have an A-frame and coupler and are attached to a ball mount on the tow vehicle.
Hybrid Travel Trailer
These expandable travel trailers come with fabric/mesh pop-outs on either or both ends.
Pop-up Trailer
Sometimes called a tent trailer, popup trailers have tent walls that collapse when being towed towing.
Truck Camper
What do you call a camper you can mount into the bed of a pickup truck? Now you know.
Toy Hauler
There are motorized and towable types, but these sport utility RVs always include an enclosed space towards the rear for hauling gear, bikes, kayaks and more.
