Thanks for the replies.
I had not thought about the weight factor and "cabinets coming off the walls." Good point.
I built a bare bones camping van on an E350 -- but didn't have the skills for either a propane system or 12V electrical work. And -- as I fully embrace middle age -- I would like to have both. On the Sportsmobile forum there are scads of fabulous DIY rigs -- made by people with much better skills than mine.
Yes, I know the FitRV reviews -- and yes, it is not only a matter of ground clearance but of what is dangling low, too.
Thanks all!
