I live full time in Durham Region in my Ford Box Truck. It would have been easier if I did not want to use the back for work related storage and transport.<div><br></div><div>The Mr.Heater works fine and unless it is blasting wind I am normally not cold. Right now I am getting 3.5 days out of a 20 pnder, soon to hook up another 20 pndr then 7 days. After Xmass I will be experimenting with a 100 pndr and some regulators, to drop down to the 31psi that is needed then hopefully I can go a month and save a lot of money. </div><div><br></div><div> For a while I lived in an Alaskan Camper on the back of a Chev pickup, in BC in the Northern and Interior. I had a radiant ontop of a propane, the windows and doors were almost always open as it was so hot in that little area!</div><div><br></div><div>John's truck cap is not insulated, I would have put up some Durofoam, shiny one side down personally. That is what I have most of in my Box truck now. </div><div><br></div><div>He might not see the post unless you email him directly. Sometimes we miss the current, newest posts due to computer glitches. </div><div><br></div><div>All in all I am mostly warm, if I had the heater in my Astro Mini Van, work van, I would be cooked out with the heat! Smaller and less drafty than the bigger box truck. </div>
