75 Overlander what supports tanks?

1975 Overlander, a bit rough, but have done quite a bit of work to it, and we like it. Yesterday I noticed that it looked like some of the belly aluminum had dropped a bit just behind the axles. On closer inspection, I can see what I think is the galvanized tray for the gray water tank has pushed the skin down. I jacked it back up where It should be and supported it. I don't have any signs of rear end separation, I can jump on the bumper, and there is no movement. The two rear frame rails were rusty but solid, I cleaned them up and painted them.
So what holds the tanks in place? Obviously, it isn't doing its job anymore. Is it difficult to remove the belly aluminum so I can have a better look? Could I just weld a couple supports across the exposed rear frame rails to hold it all up?
Just want it so the tanks don't fall off while dragging it down the highway.

You have big galvanized boxes sitting in a steel angle frame that is held up by 3 scrawny little bolts...that is all. On mine the only thing holding anything up was the belly skin, I cut that loose and it all came down on my head.

The bolts are at the rear, the forward section of the frame is hinged to a cross member.
