Condensate
It finally quit raining long enough that I could swim out to Gypsy Rose and see how she is doing. The rear window track was overflowed with water and the right side rear window was too. I'd sealed these guys up pretty good with goop before we left on our trip to "Sunny CA." (ha! it rained and snowed worse there than here!), and we had a lot of condensate problems on the trip, so I'm pretty sure it's not leaks. At least then I could wipe it up each morning. I've got a couple of those things that catch moister in the air in Gypsy, but I'm still getting a lot of water that they don't catch. Any suggestions? How about if I leave the roof vent fan running, or put a summer fan from the house in her? I noticed a big rental class C parked next to us New Years Day had really bad condensate too so it must be a common problem. Our old class C had so many holes in it we didn't have condensate.... just dew.
Cheers, John

Cold weather outside, warm inside; add moisture from cooking, showers, and just breathing equals condensation on cold surfaces. High humidity climates makes it worse.
Ventilation (ceiling fan, etc) helps some, exhausting moisture at source, ie, hood when cooking, fan when showering helps a lot. Chemical water absorbers help a little. Running your roof airconditioner on coldest setting will remove water but can be uncomfortable. But the only serious solution is a dehumidifier (esentially a refrigeration unit that removes water by condensation on the refrigerated coils); cost $250+ and needs 110v. We have lived full time in our motorhome over many freezing winters and that is what we have learned.

Your window tracks should have a slot along the bottom on the outside for drainage. If you sealed them up, you will make water incursion into your coach worse.

Make sure they are not plugged with dirt, pine needles etc.

John,
During the winter I open a roof vent about an inch. This allows the air inside to remain the same humidity and temperature as the air outside. I've never had the first bit of trouble with condensation...and it keeps the air from becoming stale in the coach as well.
