I have yet to figure out just how they provide repair parts...
I asked for pricing on three of pieces of interior panels for my 2015 Coleman. I want one of the cabinet color, one of the wall panel and one of the ceiling panel, 7 months ago! I have yet to get any price or even if it is available. So far I have managed to do some creative swapping in concealed places to get what I need. This ain't a friggin' NASA rocketship y'all.
The lack of parts apparently is a major issue when it comes to warranty work too.
