I like the japanese mini trucks. They have heat and air. You need to lift them a little to put atv tires on them, but that's cheap to do. They are quieter than an atv, but I stuck another muffler on it in front of the stock one. It gets used a lot around the farm as well. So far it's made it 11 years without breaking down. In the mountains it's better to use an offset rim that kicks the tires out a bit for a wider stance for the steep off angle trails. The 3 cyl has plenty of power for hauling heavy loads. I honestly can't remember the brand as it's camo now but think it was called a mighty truck.
