I am still having issues with my portable propane tanks getting REALLY cold. When it is about 15 degrees ambient temp, the tank compartments are running near zero. In doing some research I ran across a few suggestions. I just need something to keep the pressure up in the tanks as the temps continue to drop. I would like your thoughts before I attempt some of these. (The attached link sent chills down my spine - but it might actually work) [

Also, what are your thoughts about using a blanket styly battery warmer on the tanks? Would it get too hot?
