Is this delamination? Something else?

I've been looking for a solid trailer to put in my backyard for a family member who is handicapped and wants her own place. Our rents here are sky high and she's on disability so renting a studio apartment is hopeless.

I found this trailer on Craigslist, but just noticed one photo showing what looks to me like delamination..not sure. I'm going to look at it tomorrow, but if water damage, I won't waste my time. Thoughts on this?
