I also have a 2001 Trail-et. It is the New Yorker. I have had to replace the wood on the ramp a couple of years ago. The wood floor is in great condition. I see a tiny bit of surface rust along the bottom edge near the floor. My trailer lives outside. I did have to replace an axle since I bent it when I hit a deep pothole. Other than that it has been a great trailer. It sounds like you got the lemon.
I personally would not add bedliner to the walls and ramps. If anything I think that condensation would get in behind the bed liner, then not be able to dry out and rust more and now you can’t see it. That can happen in the bed of a truck. Also grit will get in behind the bed liner on a truck, will act as sandpaper on the paint and wear it off further taking away the protection.
DH removes our bed liner about once a year on the truck to really wipe it out and get rid of any crud that gets in under it.
I have rubber mats on my sidewalls that go to the floor so that acts to protect the sidewalls anyway. I am not sure if that was an upgrade on the Trail-ets. I bought this one as 1 year old and it has a number of upgrades so that may be one.[/QUOTE]
Mine has rubber mats up the sidewalls as well but there is rust at the bottom which is why they were considering the bedliner. This would be a coating, not something that could be removed and cleaned behind.
