Clarifying With Pictures
A class "A" starts with a "stripped" chassis like this.

A class "A" diesel pusher starts with a stripped chassis like this.
Note the engine is in the back.

A class "B" starts with an enclosed van like this.
The RV manufacture often extends the roof upward. I am not sure if the RV manufacture can purchase the van without the steel roof.

A class "C" (also a B+) starts with a "cut-away" chassis like this.

The cut-away chassis has no rear wall to provide walk-through capability.
Shown here with seats, many instead are purchased with a cheap plastic disposable driver seat for lot driving only. The RV manufactures will then install seats that match the rest of the RV's interior. RV manufactures buy the "RV-specific" package which lacks floor covering and outside mirrors, but includes attractive front chrome grill-work, power windows and door locks. It also includes two different antennas, a shorter one for an obstructive cab-over bed over-hang. Options can be a more capable alternator, keyless entry, and a radio. I am sure I left out some things, but you get the idea.
