I wonder if insulating the space under the mattress might also help, which could easily be done by adding a foam mattress topper. We have a 1" thick topper, and often camp in the winter (where it can be in the 20s-40s), and while there can at times be water dripping down the insides of the windows, particularly when cooking, we have yet to have any condensation under the mattress.
