Rippling on my TT

We had a Crossroads Sunset Trail that suffered delamination caused by heat. It sat on a lot in Myrtle Beach NC for an entire summer facing west. We used it for three years, had CW repair the roof and it never got this bad. I sold it a few months ago to a neighbor who knew the entire history. He has done extensive renovation and found almost no water damage despite the delam. Never-the-less, it significantly reduced the value of the TT. Walk through any large campground and almost all of the fiberglass units over 5 years old will show some rippling. I think it is a shame! lizzie
