I need a UTV to access a property in winter.

I would like to get a UTV, put on tracks and use it in winter. I assume I need a UTV above 600 cc's. I am considering a Rhino, and will also look at the kubota and Ranger. Altitude is around 4,500 feet. Access is on a Forest Service road. Snow storms bring 2-4 feet max. over a couple of days. I assume going in and out every 12 hours would keep the 2-3 mile route open.

Summer use would be mending fence, spraying, etc. I need to carry supplies in winter, two people and a large dog in the bed. Fun in the summer will be with a dirt bike, not UTV.

Ideas as to the Ranger, Rhino or RTV 900 for this type of use? Anyone use tracks and have info on what works.
