The Class B+ Motorhome is ideal for those who want an easy-to-drive RV without sacrificing comfort. It's like having a whole house in a van, complete with a bedroom, dinette, shower, entertainment zones, and living area - and you're only driving a van. The Class B+, also known as the Camper Van, is a van-based vehicle that is very fuel-efficient and can be fully winterized with a high-BTU heater, heated tanks, increased insulation, and double-glazed windows.
