Exterior damage, need advice :(

:SWell I turned a little too sharp too soon pulling out of my spot in the backyard on Friday heading out to the lake, didn't see what I had done til I got there, put a damper on the evening because I am a little OCD about taking really good care of my belongings, but like the wife said, could have been worse, other people have worse problems and it can be fixed...
anyway I caught the 'trim' that joins the corners together & ripped it out.
I am a pretty handy guy & If I can repair it myself I would prefer to, but if not I'll take to the professionals.





I just want to see if I am on the right track as to how this might be repaired.. I am assuming the the caulking covering the screws has to come off, followed by removing the trim insert, removing all the attaching screws & caulking, then removing this whole piece top to bottom, then either straighten out, or replace & recaulk and put trim insert back in.. if anyone has any suggestions I would appreciate any help, first battle scar the trailer, gotta slow down and watch them mirrors. :(
