Red Dragon Propane Pre-heater. I received it new with my airplane. Tested it for 2 minutes and never been used since. It is a 12 volt connection. Easy connection to car battery. Just need a propane bottle. These are very good heaters. I just have electric at my tie-down. Easy carry box is included. New they are $400. Selling for $150 for quick sale. Live in Girdwood, but work in Anchorage.
