Wow. You did a beautiful job! I'll have lots of questions for you when it comes time to redo the bay. My tanks are plastic (polycarbonate?) My first concern was safety so we could at least take short trips for now and not worry about the possibility of a holding tank falling out on the highway. We've only worked from underneath so far. We replaced some of the rusted sheet metal on the bottom of the floor with galvanized sheet metal and bolted on a few I-bars to replace the original rusted through 1.5" square frame cross pieces. This is all temporary until I can go back and do it properly like you have done. The main 3" U shaped frame pieces are still in pretty good shape. The rust on mine also involves some of the bay to the front of the wet bay, the stairs and the engine battery compartment.
