Fiberglass wall bubble

Another potential cause of delamination is a lot of use in cold weather and failure to remove moisture from high humidity. Some close up all the windows and vents and crank up the heat but are making it worse and allowing moisture to migrate to the exterior skin where it condenses. Even *IF* an owner caulked the exterior periodically, it could still have delamination going on.

If you really, really want this particular TH and the owner was willing to work with you, I'd hire a good RV tech to do a thorough inspection. Any used RV has the potential for issues going on you can't spot easily. Even new RVs can have bad leaks. What it you decided to redo the area and found it was way worse and that the whole side of the TH needed redoing? :E

We have a small bubble on the fiberglass on our slide. Luckily it's just from a screw head that was never tightened down enough.

If it's a small area (say under 1sft) with no other obvious water intrusion issues, I might ask for a discount and plan on repairing it.

If it's a large area or multiple areas, walk away.

I have a 2012 5er and the outside is in pristine condition. Why? Because I check it about 2-3 times a year for any sealant issues and take care of them right away. Sure, the decals show some age, but that is it.

A picture is worth a thousand words.

Here is a post about delamination I did some 14 years ago

Then you have one of the very rare units with none. Seriously, go walk around some parks and look. If you are expecting pristine, you will be sadly disappointed looking at the used market.

Agree. And I see a lot of them in the business. Small delamination is pretty common. I normally don't worry too much if I can see where is it from and have good access to fix propperly. When they are on the roof edge, compromise the structure or are imposible to diagnose/fix; I avoid them.

I hear where you are coming from. Many persons just own an RV for short terms for a trip and get rid of them. You would be NOT surprised how many are not washed or waxed. How many people check tire presure before they leave a CG, but then wonder why their tires failed.

These problems are more related to no not enough glue that water intrusion. I have see whole sides loose and no water intrusion anywhere.

Given that OP's delam is under a window, I'd bet money it's from water intrusion at the window.
