Does a Class C motorhome have a regular frame? Something like that might be a good starting point and the 70s Dodges are plentiful.



No, that is a unibody van frame. The front 1/2 is a box frame, bolted to the standard unibody van undercarage. That van undercarage goes back to behind the rear axle to the normal van rear crossmember where the rear bumper would be bolted on, then they weld the motorhome rear frame rails to the rear of the van's bumper box and use the floor to support the frame.

I have repaired many of these messes when people try to pull huge tounge weight trailers with them. They last for a several years, then the rear camper frame, hitch and all begins to sag. I have to go back in and try to rebrace the van bumper box and rear camper frame so they can still pull their trailer.

Go ahead and stick your head under the rear of your camper, about 4' from the back bumper you can see where they scabbed on the "frame" to the rear section of the cross box. Gene
