I ordered 14 feet of the stuff but before installation I'm going to drill some air holes in the bed plywood under the mattress to allow more air circulation.
Heat, body heat or otherwise, isn't the problem. Water vapor is. The warm, moist air released by breathing all night in a basically closed space (the trailer) is condensing on the cool walls by the mattress when the dew point is reached. It's because little air circulates there and that part of the wall is colder than the more exposed interior walls.
The Hypervent product sounds interesting. When you get it, please let us know whether there is adequate space to put it between the mattress and the walls.
