Uneven Slide out
I have a 2006 Fleetwood Discovery 39J. I just noticed the passenger side slide is a little uneven at the top. The front top does not close completely, 1/4-1/2" gap at the top so the seal does not seal. Also appears to be closer to the ceiling at the front vs the back and the front is about 3/8" higher than the rear of the side. Any ideas as to how to adjust this?
