What is the size of a class C motor home?
They are smaller than a Class A (usually a bus-type or a fifth-wheel motorhome) and bigger than a Class B (usually the size of a large conversion van). It is built on its own chassis and driveable, but it's the perfect size.
Me? I prefer the travel-trailer. You can haul them around on a van or pickup and use the van or pickup to go into town. The travel-trailer is big enough to sleep 5 or 6 but doesn't have the bulkiness or drag on the highway as a fifth-wheel. But a Class C fits the bill too.
