Look on the inside of cabinet doors, especially the kitchen, for Shasta coach specs. Look on the inside of the drivers door, if there is one, for the chassis manufacturer specs. Not saying you will find any there but that's where mine are, not a shasta though.
Curious what your plan is? If I knew I had time, which I dont, and could get this free, it might be a fun project. But it would have to at least start and not have any major leaks.
