I had this pup since around January this year. It was given to me by my Uncle. It took a beating in the snow storm we had 2 years ago. The weight of the snow and the AC unit popped the support bracket loose. Not to mention my uncle clearly didn't read the care book that came with it. Stating to never cover it with a tarp. I'm sure that and the snow produced the cracks in the top. Mostly up front. Since I got it. I have been reading a lot of how people repair the ABS and so forth. Me, I went a little further than most I have read. My goal is to use bed liner on it. In my state they want like $800 to do it. That product. Its very reputable and VERY DURABLE. I see a lot of people patching the hair line cracks and even the bigger gap cracks with all sorts of products and some see to work quite well. I also read a lot of people use gorilla glue to get the top glued back down. This is my take at it... Screw the ABS. I just spend the last 3.5 hrs. Removing the AC unit and the hold down clamps and completely pulled the ABS roof off. I thought I had about 1/3 of it that was laminated (noticeable). Boy was I wrong. A whole other 1/3 was still stuck but not very well. It pealed up and sounded like a sticker. Now when I got the the very back like a foot and a half from the back of the AC unit to the very bottom it was ATTACHED. TO the point where it took a very fine bit of foam off when I removed it. I Saved the plates behind the plastic where the hold downs were and I will reattach them. I also am going to buy a new awning rail system and come up with a way to install it. So now I need to clean the top. Fill some foam dings and take it to a shop and have it sprayed. I figured the ABS was crap it really wasn't doing anything other than keeping the foam from getting dented. I am sure it did a little with support but can't imagine much at all. The liner product I am choosing is much stronger than the ABS so once its sprayed the structure should be stronger than it was originally. I'm going to attempt to add pictures of my progress. I haven't read anywhere on here where anyone has ditched the ABS and simply sprayed the liner to the foam. Its a closed sell foam and it should be fine. I will definately make sure it wont eat it up. If it wont spray directly to it. I'll surely find a bonding agent paint to shoot it with first.
