Welcome neighbor!
Love how everyone is scared of the doors! And offering advice on something completely different than what they are looking at.
The basement doors I wouldn’t worry about at all. I would worry about the sidewalls! If the sidewalls look like that then I would pass. If the rest of the RV looks good and the price is right (and I believe this is the same one I came across) the basement doors wouldnt worry me, and yes they are delaminates, But They would be fairly easy to repair it would just take some time to do each one right.
I would go look at it. Is this in iL because I believe I’ve seen this one on Facebook market place. If it is for that price I would seriously consider it if the structural and mechanical part of the MH checks out.
Good luck!
