not to my knowledge but i will say this . We had a 1999 and now a 2006 and it is for sell and now we have a newer one being restored 2008 . and the 99 I had problems with the screws backing out of the channel but not with this 2006 at all. I have heard of others seemed liked in the 90's with the screws backing out of the track on the side. As for leaks like any camper you have to check around the windows and all seems for any gaps and seal.
