On the other hand, I bought our camper with identical issues on the front left cab over. De-lamination a bit larger than the size of my hand plus a couple of other smaller issues. Intended to repair it as I've done a couple of jobs like that.
Ended up sealing the leak temporarily(clearance lights). 5 years later no other issues and still haven't reworked the corner.
It's a great camper for us. We're just using it. Saved a lot of money compared to the market prices for the same camper at that time.
As others have said, you don't know what's underneath the skin so you would need to make a judgement call. If you were to need it repaired, it's a cheap fix only if you do it yourself. If you hire someone else to do it your talking about a lot of money.
