CONDENSATION on windows in winter

The indoor humidity is about 48% to 62%, but I don't have a meter that gives the 24 hr high/ low.

I should clarify the reason that I care. It's not the cosmetics of beads on the window and it's not concern for damage to the TT. We are in the snowy mountains for skiing, and we have lots of wet gear at the end of the day that needs to dry out before the next morning. I'm concerned that the accumulated moisture on the window will just be eventually returned to the air and my clothes/boots won't dry as well (starting a ski day in wet gear is not ideal). So, I'd like that window moisture to be discarded somehow or redirected to the dehumidifier.

The window covering option seems best (creating double pane windows) but this seems permanent? Do you remove and re-apply it each year for the different seasons? Is there no "super sponge" option for wiping windows and collecting that condensate?

If you go the shrink wrap option on the windows, yes, you do remove it annually "if" you want those particular windows to open.

We leave ours on for as long as we can. The weather in the mid-west is totally unpredictable. The plastic film helps on spring campouts, so leave it on. Come summer, the weather can go super hot, high humidity overnight it seems. If the film is still on by then, and we use the AC, we leave the film on. It helps keep the AC air in and not let so much heat in. When we go boondocking under tree cover in the summer, then we want the windows open so the film comes off which is quick to do. It does take time later to clean off the little left over tape residue. If you never want to open a window, you can leave it on as long as you want. That said, after about 3 years the tape may start coming loose or you knocked it and it broke loose.

The plastic film greatly helps keep the heat in, during the cooler weather, and it stops the sweat. If you do a lot of cool weather camping, the heat savings and dry windows makes it worth it for us. The cost of the film, is about $13.00 for our 32 ft camper. And we do not use all of it from the 2 kits. It does take time to put it on though.

High humidity does create mold and rusted screws/metal in the camper attic. It is something to be concerned about if you plan on keeping the camper a long time. Just 2 people camping in those conditions is enough of an issue for the attic molding/rusting problem to be there as the years go by. Adding attic vents, does help this and lowers the camper inside humidity. Trying to dry out wet heavy cloths makes it harder to keep the humidity down. For sure, try and help the problem with high humidly.

On the window frame drains, not all camper windows have drains. If the window opens, then yes odds are high it has drains from leaking water from the seals on the opening window. If you have windows that do not open, like a big picture window, entry door windows or some slide room end wall windows, odds are high, that style window does not have drains.

Good luck and let us know what you come up with.
