Dave, there are several companies who build motorhomes on Freightliner cab and chassis; a class B motorhome albeit it a very large one; i.e., a motorhome with a Freightliner truck cab. But then there are many companies using the Freightliner custom chassis for their motorhomes; class A motorhomes that look like a bus instead of the truck cab. You've seen lots of them on the road but just didn't know which chassis was under them.
