I intentionally waited for a severe rain storm to check out an Itasca Ellipse at my local RV dealership. The full wall slide was extended out. Water was pouring in from the middle of the full wall slide and on to the dining table. After the rain subsided and the water was removed the salesman stated that the leak was due to "blocked weep holes". He pointed out two small holes located outside at the top of the slide out about 10 feet apart. The holes were about pencil sized diameter. I was stunned by his answer. I assumed the weep holes were to allow any water that accumulated on top of the slide to slowly drain out before retracting the slide back in to limit any puddles on top of the slide that may end up on the floor inside. How can a blocked weep hole allow water inside the RV? What am I missing here? thanks........

I don't think you're missing a thing. A slide should seal regardless of "weep holes" or not. Heck our 2002 Dutchman TT doesn't have weep holes or a slide topper and it doesn't leak.

Well the trip did answer one other question for you also, you found out what salesman NOT to deal with.

I agree with Mr. Bruce, the slide seal should prevent any water from entering around the slide.Our 2008 Dynasty with four slides never leaked as when the slides were opened, the seals touched and sealed the opening to prevent water intrusion.Our coach now has air seals which also work well. But, like with any seal design, everything needs to be kept clean and clear of debris.Safe travels,MM.

Weep holes in the slide? Just what an rv needs, more places for water damage. Sounds like another lie.

This has happened to us. The weep holes are for the slide lock. It can fill with water when slides are out and should weep out the holes on the exterior; but if blocked the water will fill up the lock and leak inside. Part of the maintenance is to clear the weep holes periodically with a pipe cleaner.

This baffles me. Is it really cheaper for the RV industry to continually produce poor quality and design rather than raising the bar for both on the asembly line? I guess so. And we keep buying it

Blocked weep holes have everything to do with interior leaks... When blocked they do not work they way they are designed and water will enter the inside... Windows or otherwise.
