I have the factory hard cab with the hard doors (the doors seal up nicely all the way around). I also installed the OEM heater and use it in the winter to push snow here in northern Wisconsin I find the cab gets warm enough that I don't need a heavy coat, the heater has a two speed blower motor. I had a HiSun sxs with a soft cab enclosure no heat and it sucked, windshield kept frosting up. After two winters and replacing the wet clutch I did some research and went with the Pioneer because of the transmission and the available options. You'll save money if you buy the add ons you want and install them yourself. In the summer I take the full doors off and put the half doors on.
