i am selling these heaters for basically just over my cost at 600 bucks plus shipping im having them imported from russia where they are made. i have been testing them in my softop 40 now for a few weeks they come with all necessary equipment needed to run fully independant from the rig all you need is the battery from your truck. the fuel tank is 2 gallons and running on low only consume. 03 gallons an hour i ran mine on medium for 12 hours straight stayed very comfy on a recent trip at 14000 feet and it was 14 below outside. max output is 3kw so 1kw is 3412 btus so max btu is 11000 btw my 40 fired right up after a full night of running the unit if i can get a dozen if these guys sold i can lower my price because i can get dealer pricing from planar. theres a guy selling them on ebay but hes pretty un reliable. message me here or post on this thread pictures coming asap or you can call me at 5306351857 im in denver so shipping is the same for the east coast as the west coast
