Motorhomes can range in length from less than 18 feet to 40 feet, and from budget to luxury. They are divided into classes that are based on the type of chassis they are built on. The smaller rigs will have a gasoline engine, while many of the larger coaches will have a diesel engine mounted in the rear of the motorhome. Buying a motorhome is an all-in-one purchase without any worry about incompatibilities between tow vehicle and trailer. Motorhomes are great when you are traveling and stop in rest stops or parking lots for a few hours' sleep. Travelers feel more secure when stopping in these types of places because they do not have to get out of a vehicle to go to the sleeping quarters. If they feel that the place they have stopped in is not safe, they don't have to get out of the sleeping quarters into a potentially dangerous situation in order to leave; they just get in the driver's seat and go.
One thing to remember is that with a motorhome you will lose living space due to the driver's space that is included in the overall length. It is usually wasted space for anything but storage when you are set up in camp.
If you want to have convenient transportation for sightseeing, shopping, etc., when you reach your destination, you will need to tow a vehicle behind.
Motorhomes lose resale value rapidly and at a much higher rate than a comparably equipped travel trailer or fifth-wheel trailer. Wear and tear on the drive train is the biggest factor that affects the potential resale value. High-mileage RVs may be as difficult to sell as high-mileage used cars.
