Wardster, I think it important to tell you that my 2003 NL has been on lots of country gravel back roads and my tie downs have been tightened to where the spring load is up the 1/8th of an inch on the torklift springs in front and have not seen this problem. My camper has done fine in that the wings have not stressed. I have seen your problem only once before on a new BF camper.I don't know what they did to repair it under warranty.
My bulge, as discussed in the other post, never showed for years until I got to using it almost fulltime. Lots of condensation. I think the glued failed on mine but won't know till I get to do the repairs.
