I noted on my ST26RB how the material enclosing the underbelly was sagging with nothing supporting it from the front-mounted fresh water tank all the way back. I installed some 2" wide x 1" deep aluminum C channel in several areas which was a great improvement. (Pic attached) Support truss.jpg
However the last trip out I noted that my full fresh water tank was sagging greatly. There are two steel straps across the frame, side-to-side. The black pipe gas line is attached to the front strap. All of that was sagging terribly to the point I'm concern about flex failure on the gas line.
When I attempted to push up on the belly cover material, it's tight against the tank bottom, and I can feel a wire or something that's laying between the tank and material. Unfortunately I didn't snap any pics of all this.
Guess I'll have to open up the bottom covering too and see how that fresh water tank is supported. I'm wondering if it's supposed to hang below the cross-frame supports as it's now doing?
Anyone ever look at that?
