I did the "red carpet" walk-through for my 2017 Winnebago 5th wheel and the slideouts (opposing slides in living room) were very noisy, squeaky and squealy going out and in. They said it is totally no...
"mine do a lot of squeeling even after spraying greasing and everything else I can do" - OK so this is very normal then it sounds like. Was yours like that from the beginning?
