Collision damage...repair questions

easy repair. water heater cover about 30 bucks on ebay, and one siding panel to replace. Since the panels are interlocking and installed from the top downward, the lower a damaged area is on a trailer the easier it is to repair, and this one's on the lowest run of siding. just remove the front trim corner piece, unscrew the lag bolts that hold the awning bracket to the side of the trailer, and remove the damaged lower panel, cut and slide in new piece and staple in place. The top edge of the siding simply slides under the piece above it, and the lower edge gets stapled using wide crown staples. The front of the trailer isn't even bad enough to mess with and can prob just be tapped out better with a mallet. It will also be accessible once the corner trim is removed. Another good thing is that you only have to work with a short piece that runs to the entry door. An entire piece the length of the trailer is where it gets interesting and sometimes need a few people to help hold a piece up.
