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.
