Hey group I hope you can help me. My driver side door on our 2011 Surveyor 235RKS is sagging to the point that when it's closed there is a gap in between the frame and the door, where water can get in. If I pull the door up to where it should land, it's sealed. So I don't want to just add more weather stripping to it. I can see there are scrapes on the metal frame at the bottom of the door frame but I don't see any damage to the hinge.
Can I place some sort of permanent shim on the frame to bring the door up? Or what would you recommend to get the door to seal again?
Pic not of my trailer but same year for reference.
