Jayco 1207 roof sagging to the center??

Ok,

  Am I the only one with a sagging Jayco roof?
  I have been unable to locate any info on the net, so I have some to offer. The fix that I have come up with was as follows, I have a 1995 Jayco 1207 and after two years of fighting with the old sagging roof and no info available from anyone right up to and including the factory, I came up with this backyard engineering.

I removed the a/c unit and then removed the inside seam trim. I had already redone the exterior center seam and put it back together, making sure that the screws were good and tight. I realized that the inner trim was held in place by small (rusty) staples and that they had rusted to the point that they had caused visible chemical reaction to the aluminum that they were punched through. After removing all of them, I could stand inside and push the roof up in the center with ease. I noted that the aluminum that overlapped in the middle either slid together and overlapped more, or slid apart as I let the roof back down. The trick would be to hold the center of the roof up and now weight the roof corners and jack the roof down until the center was back into place with a slightly elevated pitch FROM the middle instead of TO the middle. I just used concrete blocks on the outside corners and two by fours inside cut to the proper length to hold the center up. Make sure that the boards are just off of center so that you can access the centerline of the camper You will need alot of 1/8" aluminum rivets, a rivet gun and a 1/8" drill bit with the drill. With the roof being held in place, drill the holes down the centerline about 1" apart from front to rear and rivet each hole, be careful not to drill too deep and punch out of the top of the camper roof. These rivets should be in such a location that they will be under the plastic trim that you will reinstall after this step, this will also ensure that you keep the holes and rivets at about the centerline to get the maximum grip from both pieces of aluminum. The idea is to keep the aluminum from pulling apart, which in turn gives the strength to the roof. I was able to walk across the roof with the a/c after this was complete with no sag and of course it diverts water away from the center seam too. I hope this helps, as I know that I am not the only one out there with this problem, I just can't believe that Jayco could not tell me how to overcome this.

Fascinating solution, does not apply to me, just curious
