x2 on the DIY for investigation, pull the side rail insert to access screws, remove
and pull the belly pan.
Sounds like the issue I've been battling...
Originally, had the side slat welds fail which hold up the overhang side walls.
I've since done my own repair for fear of attempt to weld would set the rig on fire.
Got most of that gap corrected but still need to adjust how the side molding fits to
eliminate the remaining.
