not to be smart or anything but most of them have 2 or 3 slides, and it’s hard to believe that if they have window problems it would only be on the back corner window…
you seem to know a lot of retreat owners, seven of them, since they have only been on the market for maybe 5 years… did they all just start leaking… how was it concluded the window was the cause of the leak, and maintaining the seal on the roof or the windows is an owner responsibility anyhow…
at my home base we have three Keystone dealers within an easy drive, I know there are at least 2 Retreats set up in the park but I don’t know the owners…
