Charlesin GA- I'm in the process of doing the same thing with a project trailer. Three places were penetrated with a tree branch. I had to rebuild 5 rafters. I also reinforced all the rafters sistering 2x2 and 1x2 for the arh and redecking the trailer. I'm having to do the work outside. Still have to install the roof membrane. I also took out the cheap skylight and tiny bath fan and will install two fantastic fan's. Since my awning was broke it's in the scrap pile with the tv antenna, I kept the radio antenna. Will also install a new roof A/C, old one was damaged by the branch.
