Rear Dent Repair
The PO, at some point in time, suffered a mishap. It appears while backing up, a blunt object rearranged the curve of the roof
Before repairs, the dent was quite deep, enough to push in the bathroom ceiling plastic wrap.
From the inside, we placed a jack and a 2x4 in place where the fan housing is. Then slowly jacking up on the housing to push the dent upwards. Just a little, then wait a few minutes to let things move around. There were several popping noises coming from outside as the dent decreased in size!
