After four years, the rivet heads wore completely through my belly pan in the very rear of the trailer. I added some sealant and some screws, but two years later the belly pan actually tore away from the screws and was almost completely loose.
There is no other rivet wear on the belly pan other than the farthest rear sheet. I haven't seen any posts out there about any other folks having this problem, so I don't think it's just normal wear and tear.
Does the wind constantly ripple the thin aluminum sheet while driving which could cause that kind of wear? I've put about 70,000 miles on the trailer, so I guess that's a possibility.
Or worse, is my entire back end shaking while I drive? My shower (rear corner) has come off it's foundation in the past and I'm beginning to think this is all related. http://www.airforums.com/forums/f446...ver-70946.html
I used a 1/8" x 1" x 8' piece of aluminum to distribute the pressure and hopefully prevent the underbelly from tearing more. I'm also going to look into Centramatics. Any feedback would be welcome.
