Depending on if Caveman built their rigs with steel frames through all the generations, it should be fairly structurally sound, most of the wooden parts are likely for framing in walls.
Rebuilding isn't hard, it simply starts by de-skining the unit and marking the order and where each piece went. Depending on the make of siding, you'll either start at the top, or start at the bottom, they're usually only held in place with staples.
As to schematics, you'll never find any, Caveman out of Grants Pass, OR, went belly up decades ago.
Simply measure the old material to cut the new. It'll either have 1x2 or 2x2 wood in the frame, along with steel angle iron (Caveman only had this).
Reico jacks you can buy rebuild kits for for $50, which rebuilds two jacks.
I have a set of 4 Riecos that are far newer for sale, $400. Been working on repainting them as the powder coat they came with from the factory was crap.
