Paint peeling on the Chevy's is a common thing.
By the pictures looks to be on used RV lot ?
So who said it delaminated because of heat ?,,, no wait let me guess the salesman...
I bought my last one off CL the guy was asking $26K , it did have good bones. I pointed out all the neglect it had and what needed to be fixed.
Just needed a lot of TLC, made the deal for $13K put $5K into it put 20K miles on it . Just sold it for $25K a few months back to get the one we have now.
If your handy and can do a lot of minor things yourself?
They are out there , keep looking.
Obviously right now it's a sellers market NOT a buyers..
Be patient keep looking on CL RVtrader etc.
I agree on the Chevys ! They ride better, better mpg ,more leg room just to name a few.
