Well if I were to find a campground that had perfectly level pads that were long enough for my trailer id be able to answer that better,.But since most camp sites are stone and a few been sand when my slides were out it did kinda sink to that side about 1/8 of a inch which isn't bad but I try to get it dead on if possible.Both slides are on one side,one is about 10 or 12ft and bunk house a about 6 ft.So yes it seems the weight of those 2 extended plus the furniture(couch,kitchen table and bunks it is some extra weight hanging over the trailer tends to lean towards that side.That is why I put them out first then level it out,it takes me no longer than if I leveled then extended slides.
