Well after spending all afternoon resizing photos, I can finally put together my repair.
First - what caused the failure - in a nut shell inadequate support, and possible improper installation. I found uneven parameter support and the box was warped downward before the front screws were installed thus inducing stress even before it was loaded. I also found one big wiring safety issue, For those that have furnace function issues, read on.
First - getting the box out. The visible screws are easy, it is the hidden one in the basement wall structure that are tough. Before I go on, Bag and label where the screws cam from as some are different lengths. I did not do this and it led to some frustration in putting things back together.
Remove wall from frame (bag and label screws)
While panel is off tighten the coax connections and check wiring. If you look closely you will see the safety issue. Hint - back corner of furnace.
Unscrew wall framing from trailer side and top and bottom. Its important to keep track of where the screws can from as the side wall one are shorter. The top and side screws go into aluminum structure. Bottom ones into the base plywood. Again look at back corner of furnace.
This is the problem area with wires lying directly on the sharp metal edge. These wires control furnace function. Mine showed evidence of chafing. GDRV-Emily @GDRV-Megan
This is something production may want to look at.
