decals when hot like in the south whee you live, come to think of it the eastern Oregon sun in the summer is about that hot, will cause the decals to bubble or peal off. mine are doing it also on my 09 keystone. I just don't worry about it, it is going to happen where ever you live, only thing you can do is get ahold of your TT company and see if you can get new ones and take the old off or wait until they come completely off then install your new decals.
