Thanks for your response wrapperman. I just read my husband your response. I guess I must have explained it wrong, he said that if it were the cogs it would go out crooked and not be flush on one side and not on the other. So I guess my explanation of the problem was incorrect. The slide is not level when it comes out, it is leaning to the back of the coach. The wipe ( what my husband is calling them) on the front side of the slide does not touch at the top, but touches at the bottom. The whole slide leans toward the back of the coach. Right now I cannot take pictures of the slide out from the outside, however when we get back I will take pictures and post them. Maybe those will help in understanding what I am trying to convey. It is not staying level on the track that it runs on.
