I was cleaning inside of camper after our last trip and I noticed that the ceiling around the edge of the air conditioner looks curled op in spots around the base it's very hard no water stains is this normal any thoughts or am I dealer bound when we brought it home the forum said the bolts that hold unit down were loose took it in and my bolts were loose and they tightened them down any thoughts?
Remove the air handler and look to see if the unit was properly torqued when it was installed. There are 4 yellow "torque tabs" that should "just" touch the roof when the air conditioner is tightened properly.

I just saw this thread after seeing the exact same hard wrinkles on the edges of air conditioner on my 2012 Roo. Mine looks exactly the same as the photo. It is also a Coleman Mach. There does not seem to be any water damage or softness or discoloring.
Now I am curious if others look the same and whether or not it is caused by water? Also, has anyone removed the cover on a Coleman Mach to access the bolts to tighten? It looks like it involves more than just removing a few screws.

Yea, my unit looks just like those pics and I studied it pretty closely. It's not water damage. The cover seems pretty tight in places and seems to "dig" into the ceiling causing the ceiling material to look like that.
