So what did you do to your Truck Camper today?

Some aluminum window frames have little slots cut in them to weep water out, like condensation. I had that on an older camper. They got clogged with dirt. I couldn't see the dirt, but I took an air compressor with a rubber tipped blow tool on the end and forced air in. A bunch of crud came out and the window never leaked again.

AShh...That could be it. Will check it out! Thanks....

Looking at your photos, that's a slider window. Water gets past the fixed window and into the slider channel, where it's supposed to drain outside through those slots I mentioned. If enough dust and dirt gets in there first, it turns to mud, then hardens to block the drains.

If you can, remove the screen and the window. Screen should easily lift out, window I'm not so sure of. Then get in there and clean it all out.

Since that happened to me, I regularly clean my window tracks. I just did it yesterday in fact and they were pretty dirty. Enough so that I would bet two or three seasons without a deep clean and they would clog.

Even if the slider channel is clean, insects, like mud dobbers, will pack mud up in there.

To test before and after cleaning, try putting some water into that window channel. If it fills and drains to the outside, good. But if it fills and sits, or worse, your seat gets wet again, then you know where the leak is happening.
