I have a 93 Winnebago Brave and I have been using it on hunting trips to West Texas. The past few weeks it has been pretty cold, usually dipping into the teens at night. The heater works great and we all sleep comfortably, but there is a considerable amount of condensation that builds up on the windows when the heater is running. The problem is not while we are camped, but when we leave. Over the interior of the windshield on the Winnebago are metal strips about 3 inches wide. When I take off, I have water leaking onto the dash and down the side windows. At first I thought I had a leaky roof, but on this last trip it was dry, no rain no snow. I realized that the condenstation is building up in the those metal strips and holding there until the motorhome rocks back and forth and then it leaks out. Has anyone had this problem? Any ideas on how to fix it? I was thinking about applying some sort of insulation but would be afraid it would get wet and moldy.
