Thanks for the reply. I am bringing it back to the dealer next week, so hopefully they can fix this. What really worries me is that the slide bottom looks like it has a curve in it and it doesnt seal properly. Thor said it probably needs a t-bar adjustment???, but I have my doubts. The factory is over 1,000 miles away, so taking it there for repair is not an option. I think this is the 6th time we have taken it in for gaps and leaks.
