Leaking Slide

Ours is a Monaco and as The Texas said, has to be level to not leak.

BEFORE you take ANY advice on here, call Fleetwood, Monaco division and talk to them. Monaco did build a dam on the bottom corners of the slides and the water WILL build up and over flow if NOT perfectly level or slightly side down. This happened to us and I was all set to redo the seals and then I talked to the experts. Lo and behold, no more leak.

BTW, this was during this past heavy rains in SW Arizona .

Definitely a seal issue and as others have stated they may not be fully "flapped out". Are your slides manual or automatic - I've seen both on a rambler, but mostly autos.

What we have found is that sometimes the seals on the side do not pull out all the way like they should when the slide is extended. We use our awning hook to slide the outside edge of the seals out like they belong. We have also discovered that if we are not level, the slides leak. If we are level, they stay dry.

My seals did the same thing. I installed some of the stair tread strips to the side of my slide and the abrasive coating flips my slide seals, going in either direction, so that they are always positioned like they are designed. This is available on a roll from Home Depot.

It sounds like this has been an ongoing issue...never heard of urethane foam used as a slide seal. There are dozens of seal designs, so it's hard to address your exact problem or suggest alterations. To better it, look at some seal suppliers or get advise from an RV repair tech.
When we have high, sustained (+50mph) winds, rain will come in at a few lower corners of the slide. The seal is not much more than an large, exterior rubber squeegee. There are no interior seals that compressed when the slide is extended. I am not impressed with the method/style the manufacturer used to seal our slides. We didn't have leaks with our previous TT's slides under the same conditions.
