Last winter I used a buddy heater. I bought a cup hold thing for a jeep, strapped it to the floor right in the middle up under the dash so it would accommodate bigger cups. Doesn't move at all. So I thought I'd try a buddy heater last winter, strapped it to that so it was at an agle, and it worked pretty well. Wasn't toasty or anything, but enough heat off from it I wouldn't freeze. Full windshield and top. Regular doors on it. I know it has a flame and everything, but I just used it for hunting, going into and out of the woods, about 5 miles each way, at a nice slow pace. I wouldn't recommend normal riding or anything with it, but for plowing or something where you are going slow and it is strapped good, I thought it'd be fine. Just be sure to have comp insurance incase it does catch fire haha.
