I see you have a 2106 bxxte like I have. I had an issue with our wall slide leaking and sticking . Both were addressed at the factory recently.They had it completely apart and did a lot of work to get it corrected. The sticking was caused by bubbles in the roof material on the slide. Now it goes in more smoothly. When it was sticking coming in, it would pop loose and actually hit the ceiling and tore a spot in it. They replaced it. Now the question I have is the motion of the slide coming in typical. It comes in at an angle bottom first then rocks forward at the end very close to the ceiling. I have a video that I would appreciate your input if it is like your slide operation. Can you look at it.Can I email you the link?
