Hi
I opened the rear belly of the Montana to inspect the water tank mounting, frame and 220V / 50 Amp wiring. When I started putting the belly back together I found the screws that hold the back end of the belly covering to the rear cap to only be threaded into the black covering. I find this quite lacking so I did the following.
I cleaned the black covering on the inside where the screw holes are with Lacquer thinner and then applied contact cement. I applied contact cement to some wood shimming material I had and arranged them so they went continually from one side to the other. I then glued them in place and fastened the black covering to the rear cap with 4 screws and washers. This makes a secure joint at this location. I then used foam filler purchased from Home Depot to seal the holes around the water tank drain and the left and right corners of the rear cap.
Here are the pictures.
