Fixing a window leak

Oh, damn, pulling the window is not what I was expecting. But, I guess I can do that with the help of a video. Where can I find the Proflex? Is it available at a Home Depot or Menards, or will I have to find an RV dealer/supplier?

If you think of the brand of stuff you are talking about, let me know.  It would be a lot more convienient if I could get it at a local Home Depot or Menards.  I probably won't be able to get to it for a while anyway.  After today, we are supposed to have rain the next 4 days....I will have to do some temporary waterproofing in the mean time.. Maybe some tape or something to get my by the next 4 or 5 days.

Looks like you are on the right track for sure

Good luck

Yes, I watch a half dozen videos. It just seemed like that one seemed the most logical and also seemed to mirror written descriptions on how to do the repair.
However, after watching another video, I came to the realization that it could simply be a plugged up water drain in the window frame. I used a piece of wire through the drain holes in the bottom outside of the window to hopefully clean the drain track. I then pored some water into the drain channel and it seemed to drain outside through the drain holes just fine. We have some rain predicted the next couple days, so I have the trailer leveled in the drive way with a rag under the window on the inside in case it still leaks. If it doesn't leak inside, then I will assume I solved the problem. Oddly, the trailer sat all winter and spring in the driveway but I keep the front end jacked up to facilitate draining the water off the roof. It never leaked all winter or spring despite a wet spring. Also, it did leak last summer. I thought it was simply my wife splashing water when doing dishes. But this year on our last trip the counter was soaked again. My wifed swore she was really careful when she did the dishes. It had been raining so I thought that maybe we did have a leak. But since it didn't leak all winter, I still wasn't convinced.

Well, when it started raining on our trip, I did notice more water on the counter and upon close inspection, could see the water running out the bottom of the window down the wall to the counter. It seems it only happens when the camper is level front to back. So, that tells me it could be something plugging up one of the drain channels in the window. I have two tubes of the Proflex on the way from Camping World, and if necessary, I will pull the window and redo it. I also agree that using a plastic scraper is a good idea.

I also checked the other windows with drain holes (weep holes) and ran a wire through them.

I will try to remember to update this thread after I verify that I have solved the issue. Others out there might want to do some quick maintenance and make sure their window drain channels are clear as well.

I hear you. I hate plumbing and water issues. I think my trailer does have the "foam" for gaskets. That is what I initially thought it was when I was looking at it. But then, I figured it was some type that was made for what it was being used for. Is it just a cheap way of doing the windows? Maybe I should consider redoing all my windows???

I like my KZ Sportsmen, but I have found several areas where the lack of quality has completely amazed me.  I realize I have an "economy" model, but c'mon.
1. The water system was completely sealed so that it required removal of a bunch of waterlines to winterize it and dewinterize it. I have since installed bypass valves to make the process as easy as turning a switch to do the winterization and then dewinterization.
2. I had to replace the brake lines on my trailer ( I have surge brakes). The originals were routed up along the top of the axle so that when the trailer frame bottomed out on the axle, it would smash the brake line. Both brake lines were completely crimped so there was no fluid flowing which essentially disabled my brakes completely.....Upon contacting KZ, they first denied that they even install surge brakes on trailers and claimed it was an aftermarket system. I called the dealer and they said NO. It was factory and all their trailers with surge brakes come with them from the KZ factory. I finally got KZ to acknowledge that they installed the brake system but could get no reasoning for having routed the brake lines as they did. I just assume it was a dumbass tech in the factory. I hope they don't do them all like that as standard procedure!!!
3. The faucet on the kitchen sink was a $3 plastic POS. If you tried to rotate the spout, half the time it would pull out of the base and you would have a geyser in the trailer. It was held in with a rubber O-ring gasket and any upward force pulled it out. It looked like the type of system they use on the quick disconnect for garden hoses except that the faucet spout is not locked in. The whole faucette was made out of plastic. I finally replaced it with a real faucet and am so relieved now.
OK done with the ranting......Should I consider replacing the seals on all my windows? This is on a 2011 Sportsmen 19BH.

Where/when is the rally. I have heard of it in past years. I really won't be able to attend, but just interested in knowing more about it...One day maybe.

Update, the leak returned. We were out this weekend and it rained all day saturday into sunday and by the afternoon on Saturday, I once again noticed the slight drip, drip, drip out from under the window over the sink, down the wall onto the counter top. I just kept a rag under it until we left and when I got home, I got up on a tall bucket and looked along the top of the window, there is clearly a breach in the seal. I will be pulling the window and re-doing the seal and replacing the window this week sometime. I really hope this is the final solution. Water leaks stress me the he11 out.

I guess I could just patch that spot with some sealant, but I would rather pull the whole window and redo the entire seal and make sure it is done right.

What do you guys think:
