Water leak on back window in 2500RL

On the bottom "rail" of the frame you will see you either 2 or 4 scuppers or water drain holes. If your window is like ours you will also have 2 or 4 water drains on the top rail, only these will have rubber plugs in the holes. I took each one of those rubber plugs out, applied clear silicone around the plug, reinstalled it and wiped up the access. Just cuz I was there, I ran a small bead of silicon along the very top edge of the window frame.

Not sure which was the fix but there is no leak any more and we've had rains of biblical proportion here lately.

I had a similar problem. I reseated the seal around the window with a plastic tool used for dash repairs on cars. I had a tech check the window and he told me that the most common problem is those rubber plugs. He does exactly what you suggested and that seems to do the job.

Had s downpour today and checked back window. Looks like water in same spot as picture of window and small puddle on floor under it. Will seal those rubber plugs and keep eye on it.

Don't forget to check the seal between the window frame and fiberglass.

This was my problem too! Fixed it. So thankful for people smarter than me or at least ones that think of this kinda stuff LOL. We had a gullywasher on our last trip and not a drop!

This topic has me both concerned and disappointed. We take delivery of our new 2600RB in the next few weeks. Our old Prowler (also purchased new) apparently had windows that were leaking inside the wall. The camper was never wet on the inside, but the walls have rotted from the inside out. Really a bad deal as it was always stored inside over the winter months, only out in the elements May through October.

I ordered a Grand Design camper because I thought that they were built better to avoid these kinds of problems. Looks like I'll be taking a step ladder with me to inspect the windows and seams when we take possession.

I would highly recommend looking over your trailer during the pre purchase inspection with a fine comb. We too purchased a Gd because of their supposed better quality. What we bought turned out to be the opposite and so far we keep on encountering issues even though we found plenty at our inspection. In a way all the issues we found should of been a warning to walk away...live and learn I guess

Thanks for the heads up. I'll start making my check list.

I had a leak in the same window. I resealed it and still had the leak. I then took a look at the rear camera mount and sealed around the top and it hasn't leaked again.
