Have a 2017 2650RK and have water getting into the interior from the slide outs. The camper was closed up for the winter but we recently moved it to the dealer for service, which is when we discovered water puddled in areas and coming out from under the slides. It could be that water is pooling around the seals and on the slide roof but when the trailer is moved, it finds a way in.
I also noticed water running along the slide track and getting into the interior when extended.
Has anyone else experienced water issues with the slide-outs? Of course the dealer says this is not a warranty issue.
