Hello, I was looking at a 2800rls this past week and I saw something that made me a little nervous. The main room slide appeared crooked. It was farther away from the wall at the top than the bottom. The dealer said that they were all a little different. I agree to that but the frame actually looked crooked when looking from the rear of the trailer towards the TV area. Then when the dealer went out of the trailer as he stepped on the steps exiting the trailer the entire slide actually moved at the top. It looked like it moved quite a bit. I would say the top moved about an inch,maybe a little more. As he stepped on each step the trailer would rock and the slide would wobble. I have been in other trailers with slide outs and have not see movement at the top of the slide. You could stand in the trailer and move from left to right ,facing the front and see the room move. The dealer didn't seem to be concerned. I would be embarrased to have my friends over and have this happen. We did go to another brand and rocked the trailer from side to side and in one brand saw no movement at all. the other brand might have moved very slightly. Both of these were ok to me. The question is : is this typical for the Sundance, when the slide is out should the moulding overall appear to be vertical? Should the slide be stable? It's difficult to describe the amount of movement to someone via the internet,or a conversation. Believe me there was alot of movement at the top of this slide. Like I said we did not see this in any if the two other brands. What are your thoughts?? Thanks .
