So I took a look at this 2015 Fusion toy hauler 2 years ago and recommended slide out rollers. So Keystone chose a slide support that is little more than a plastic shoe to drag the slide on top of. This is a BAL cable driven slide with the light duty drive unit so needless to say, over time the slide weight deformed the shoe at the corners which increased the drag which caused the slide motor to struggle to move the slide. It became so bad that the only way the slide would move was if the trailer battery was being charged. So join me as I add rollers to the slide and see if it helps. Thanks for watching!
