I don't want to rain on your parade.... but unless you are very mechanically skilled, you will be better off selling it for scrap. There is no gasket, caulk, or piece of rubber on that thing that is not completely dry rotted and cracked. It may also have a good bit of mouse damage.
It may not be molded/rotted if it's spent most of its life in Arizona.
Sadly, I concur !
About 15 years ago, my neighbor got one very similar to what you have. He gutted the interior and did his best to re-caulk everything on the outside. Then he spent a fair amount of time rebuilding the complete interior while his wife sewed new upholstery that they put over new foam. The interior was almost new except for some of the mechanicals.
They used is a couple of times, decided it was too small and
IT STILL LEAKED !
