I have a '95 Featherlite 7x20. Bought it new in '95. No welds have broken. Axles are the original ones. We did tear a piece of trim off the back dragging in a bull-rope tore it off. Stupid bull!  Aluminum floor is good. Have replaced the rubber bumper. That's a chore. I like the five hinges on the back door as opposed to some other trailers with 3 hinges. Every so often I knock the hinge pins out and put some never-seize on them. Keeps the back door quiet.

Lights are pretty much trouble free but easy to replace. I try to take it to the truck wash 1 or 2 times a year for a chemical wash as I was told the cleaning protects the aluminum. I put bearing buddies on mine last year which I like.
