Hello all. I am looking at a sales ad for a motorhome very close to my house. Does anyone see the "wavy" or puffiness in the basement area? Seller tells me there is no water damage but I've never seen this before. Any clue?
The compartment doors on my motorhome are made with two pieces of FRP with Styrofoam in between. There is no adhesive bonding them together. They look very similar to what is in your picture and varies with the heat/cold.
I know this because I damaged one of the doors and had it apart to repair.
Now, if it were the side panels, I would look elsewhere.
