if you are dead set on rebuilding this camper bravo for trying to save an oldie...first off build a stand to set the bottom on cause there is nothing left of your floor..then support the overhead to keep it from collapsing when you gut the inside..take lots of pics as you tear it out so you have refernce photos when putting it together..then take measurements of the frame because you will need to build a new one..and it will take time..research sources for materials to save money..you should be able to build new frame for less than a grand..
