I went through the same things recently looking for a new UTV. I looked at all of the major ones around here, and for me, the most bang for the buck came with the Ranger. The Mule was a very close second, but it lacked top end speed for occasional road use and it rides a bit rougher. The Mule does have a larger bed, and it's metal. Both have available aftermarket cabs. They're expensive, but still far less than the Kubota. The Kubota offers the heat and A/C, but when I'm out working I'm already dressed for the weather. Just blocking the wind would be the biggest thing in the winter. From what I've seen, the mini trucks appear slightly larger than the RTV 1100. The Bobcat offers some interesting options, but from what I recall, the cost approaches that of the Kubota when you start adding those options.
