Our new Jayco 31.5RLTS 5er had a panel in the basement that hid all the wiring and duct work, as well and the transfer switch and 1500 watt inverter I had installed a short time back. The problem is that in order to access anything behind that wall the whole thing has to come down and there are light fixtures, a battery switch, an electrical outlet and the outdoor entertainment outlet all of which are wired into the "wall" making it hard to remove and replace when you need to access the space behind that wall.
The material that this "wall" was made of was nothing more than thin luan type material and was very flimsy. In the more expensive Eagle and Pinnacle models these walls are made of heavier material and have access panels in them, not so with the SuperLite.
This weekend I replaced this "wall" with a piece of 3/8 plywood and cut 2 large access areas in the panel. I then cut 2 covers for the access panels out of the luan material that was the old wall. I then covered every thing with grey felt material similar to that which the original wall was covered in.
Now if I need access to this area I can remove either or both access covers with only 4 screws each and I'm in. Not perfect, but much better than what came from the factory.
