With all the discussion here and on Expedition Portal about condensation in pop up campers, I am wondering if anyone has thought about or tried using a water proof breathable material like Gore Tex to make a the soft liner for their pop-top? On my previous camper (pictured) which was a 100 series Land Cruiser with a Westfalia style pop top, we made the fabric sides out of Gore Tex Pro, and never had any issues with condensation on the fabric at all. We also only had minimal condensation elsewhere - primarily on the windows and a few places where there was exposed aluminium - even in cold damp conditions with two people in a much smaller volume. Similarly, some one on ExPo was wondering why US manufacturers don't use breathable cotton canvas liners as they help with condensation. I don't personally want a canvas liner, but a Gore Tex liner may work in a similar fashion.
We have a new Fleet, so we have no need to replace or upgrade our current PVC liner, but I am considering making some window covers out of left over Gore Tex from my previous project. These would be cut to be the same size as the current clear window covers with a velcro border. The idea being that you would leave all the windows 'open' and then velcro the Gore Tex panels over them. This would turn about 1/3 of the liner area into breathable fabric. Before I spend the time sewing this - has anyone tried anything like this? Any thoughts on whether it would make a difference?
