I have a 24 ft and have found the troublejust not worth the extra 2 to 3 up temp. Where are you in E.Tn and I will let you haul mine on and off a few times and see what you think. I have been testing a liquid solar blanket I picked up in Pigon F. and have seen solar cover like proformance. I am only loosing 1 to 3d at night and picking it back up each day. I have been able to hold 83 to 85 for the past few days. Where you running?
