Presently, we have a Dodge van outfitted with cabinets and seat/bed from Sportsmobile. We mostly sleep and shower at truck stops when travelling. We would like to go to a Class C next. We have gone to RV shows, dealers, factories, and searched the Web. All manufacturers seem to use the van chassis. Do you know any brand that uses a cab that is larger than the van; say like the Ford F series chassis with a cab size like that of a standard pickup truck?
