Agreed. Pass and move on, nothing to see there.
I bought a nice 14' popup with a slide from a guy that said he had a small leak in the corner. Had just a touch of discoloration in the tent on one end. Ceiling felt firm, no soft spots on the floor, rest of the camper was in like new condition. promised me it had been fixed and I could see the work where he had put some new tape on it. Thought I was getting a steal.
Bought it and used it a year. The next spring when I went to de-winterize and get under it, saw that the whole corner and front panel was rotted out. traded it in for a $1300 loss and considered myself lucky to learn the lesson on a Used Popup instead of a used TT or MH that could have cost me 10x or 20x that.
If your ready to risk taking a beating if it IS a bigger issue, your better off going to vegas and putting it on the roulette table.
