You are not going to find a parts list. Nearly every RV is custom built so nearly every one is different. Many of the companies that supplied parts for that RV have gone out of business or are making completely different versions of those parts.
It is very hard to find parts for a 35 year old car with 200,000 units built. It will be impossible for a 35 year old RV with a few hundred units built.
So, you need to start all over from an empty shell and build the RV back from the inside out. Not looking like such a great deal, is it?
