Window leaking??

[WELLSweR]

The past week it has been raining and each time I check on the fifth wheel (2012 3150RL Montana) there's water in the large back window where the window slides to open.. Not a lot but does anybody else notice this? I wipe it dry but it just gathers again.. am wondering if some may be running inside wall and will cause damage.

This may sound dumb, but try opening the window and close it. Sometimes the drastic temps. Will cause the seals to expand and contract and there just might be a small piece of left over metal or aluminum at the top to keep it from sealing properly, being its a new camper. I have also seen where they cut the window openings way to large for the window. Either way it's under warranty, have if fixed pronto. It doesn't seem like it would get into the walls as you describe it, but I can't be for sure, best to have the dealer fix it. Happy Camping, Sam

Not sure if this is causing your problem but make sure the drain slots in the bottom of the window frame are open. They are very prone to get clogged up with debris. Basically the window frame should drain water to the outside through a series of slots in the frame bottom.
