The Class B motorhome isn't as popular as some other motorhomes, but it is gaining popularity in some RV circles. The Class B motorhome is often called a camper van, because it is a van body on a van chassis, but usually with an oversize body. They are smaller than Class A and B motorhomes, and aren't suitable for large groups or families. They usually don't have as many features and accessories as other models, either.
However, these smaller units are perfect for a small family or couple, and some of them even come in 4-wheel drive models so you can access off-road areas that other motorhomes couldn't touch. These models are becoming more luxurious, too, so if you haven't looked at them in a while, you should check them out at your local RV dealer.
