Ok it lost my letter on the last posts so here it is again: Problems:
Water heater didn't work on propane, wired wrong (I fixed)
LED running light (driver side) resister was broken because it was connected the blue wire of the side control EXT and not the blue running light wire. The installed pulled the wire to get it close enough to connect. (I fixed with new part)
Grey water discharge pipe was loose and leaking (dealer fixed)
Sway Command didn't work (dealer removed)
Bathroom door would bind when closed (dealer fixed)
Bed felt like you were sleeping in a hole, found out the 3/8" plywood was flexing the braces were only screwed to it and the screws puled though. I fixed it by adding a 3/4" plywood then glued and screwed it now it's solid
The panel below the fridge would hit the side of the dinnet and the floor when moving inwards, I trimmed the side and bottom off in my table saw and remounted.
Wires behind the panel would get dragged when the slide as brought inwards, so I tie wrapped them together. Watch the gas line and fridge electrical these need to move.
