Hello,
Replacing the freshwater tank is a pretty involved undertaking. Expect having to tear out much of the surrounding structures to get to it. The flooring might be rotted to the consistency of barkdust under that tank. The steel studs holding the old flooring down might be waiting to puncture the tank even more unless removed, their tops rusted away and now present themselves as nails. The rubber sheet that the tank sat on is probably dried out an no longer offers a non-slip surface that it originally did to keep the tank in place. You may find that other structures that alway sat on this flooring have also sufferred structural setback and need attention, shimmed or materials added/replaced.
Don't be surprised if a tank replacement is not redilaly located (INCA made the original and they were not interrested in making a replacement). Or that no local plastic shops want to take on the repair or fabricate a replacement. Your tank is weldable and repairable, go airless, it is low density PE (polyethelene, spelling is something like that). This is something that you can do yourself.
You could go with a simpler tank design, smaller, but if you install your overflow differently, end up with about the same effective capacity. On my 1980, I lost probably 20 gallons on the first steep hill.
If your tank still has original copper tubing to tank fill, this is to rigid and the tank will crack their. Swap this out with flexible plastic tubing. Stock on later busses.
I also beefed up the bed supports, rebuild the fridge shelf, added modern computer fans for the fridge. In general improved upon the factory design, with future access a consideration.
