On the street side in the same location, there is one missing rivet but no pucker.There is no visible damage to the interior wheel well or other indication of why the panel might have been pushed rearward. There are no other signs of a problem. No pictures available and we can't go back and look at it again. I know it's difficult to diagnose from afar, but is there any chance this is an early indicator of a frame problem? I found no evidence of soft flooring in the areas I could access.
The 34'ers have a very long overhang, which causes a lot of stress on the frame just behind the axle mounting plate, & this is where the "pucker" is. I have seen this quite a bit, & yes this is a symptom of frame issues. The end of the outriggers tend to sag in this area relative to the frame rail & the frame rail itself sags gently. These trailers really need a "sister rail" between the axle mounting plate & the "L" attached to the bottom of the frame a couple feet aft of that. If you place two hydraulic jacks at the rear of the frame rails, & lift until you see the "pucker" disappear, this is when you would install the "sister rails", thus removing the weak point in the frame. Keep in mind that this doesn't happen on all of the 34's, but I suspect it is dependent on how & where the trailer was used.
