Welcome to the forum and congrats on the new to you trailer! Don't let the damage get you down, just figure out what needs to be done and get her fixed up so you can get out and enjoy it when camping season gets here. And yes, I have no doubt you will have many more things that need attention; that's part of camping and RV ownership - the FUN....the
FUN and memories you make will far outweigh any inconveniences you may encounter
