We had constant problems with the slider. Our’s has a full side slider – I’m guessing it’s about 25′ at least. I had brought it in to Camping World 5 times. They’d “fix” it, it would work once or twice then it wouldn’t work again. Finally I took it to the factory and had them take a shot at it. They fixed it. Seems that Camping World didn’t know how to align it properly. CW gave me a line of crap about how one side or the other would usually stick out up to 2″. B.S. The factory aligned it and it’s within 1/2″. We’ve not had a problem since then with the slider.
