Hmmm...he may want to reword that description to read "large refr"...instead of "large refer."
I believe that is coach #456. Be aware that if that coach has been outside in the rain without the slide seal inflated you could have significant water intrusion and the potential for mold inside the coach. It could certainly be converted back to a bedroom and full bath but it would not be inexpensive since none of the original components are available.
Not that I'm considering it - but..... anyone care to ballpark a cost of the slide repair, assuming it's almost as bad as it might be?
