Prolly most of us have thought of this at one time or another. When I get a XLWB M809 to convert into a motorhome, whether it's a -14 or a -20, I want to mount the old body on a pair of 5 Ton trailer axles with a new frame and a semi-permanently mounted set of drawbars. Of course, I'd have gone with Battleship Gray if I'd had my druthers, RidgeRunner.
Serious technical question, with a cargo bed rigged up as a trailer like this, is there an easy way to make it a dump bed for materials while leaving it hitched to the tow rig, or better yet, drop the rear on the ground so a car or small truck could be driven (or winched) up into the bed like a redneck RORO?
And this is redneck engineering par excellence.
