Over the past Memorial weekend we pulled into an Indiana State Park, filled our water tank, and got into our site. Behold! The left front landing leg would not lower! Anyway I jumped one of the solenoid and got unhook. (even managed to get fairly level)
once we got home I traced the problem to wires being broken at the leveling system sensor mounted just fore and above the front axle.

Upon further inspection it seemed that the harness was routed under the tank low point sump and upon filling the tank it had flex enough to stress the wires over the last couple of years. (I'm guessing) Fixed the harness (thanks Jim at Big Foot).
Now for the modification: Cut into the underbelly and raised the tank using a jack. ( it's hard to see in the pic but the particle board is really bowed)

1/8" x 1/2" angle cut to 31 1/2" to fit between the rails, notched

Fit between the rails and secured with self tapping screws

As you can see with the weight of the tank on the installed angle the bowing is so bad I can put my finger between the board and the rail

I was very surprised to see only one metal strap under the particle board from the factory. Anyway I hope this mod takes care of our problem. I may go ahead and do the same thing on the door side of the tank too.
