lost a part last night

Few years ago bought a 78 Dodge Motor Home, took it on vacation, about 60 miles from home, I heard a scraping sound, stopped, looked underneath, thought maybe the hanger bearing(2 piece drive shaft, didn't see anything amiss, drove a little further, heard the same noise, went to the rear bathroom to get a work shirt, looked at the bathroom floor, slanting to the back, went to the back and the add on rv frame had broke behind the van frame. Called home and told my dad to bring my pickup, some gas for the generator and the sawzall, I emptied the box on the back, and tore the box apart while waiting, we cut part of the frame off, and ran ratchet straps around the top to hold the rest of the frame up, brought it home and thats where its been parked since.
