The only vehicle you are likely to have access to that works in 2' of snow is a snowmobile, and it has some serious limitations.

I am not convinced there is a perfect vehicle for GOOD. I think 4WD is good, as is above average ground clearance. Probably better to have a smaller rather than a larger vehicle in case you need to maneuver in tight spaces. More on board fuel carrying capacity is good. A roof rack gives you a lot of flexibility with cargo carrying. A vehicle has protection from the elements (and at least some from 2 legged predators) that is not available on a motorcycle. But a motorcycle does have flexibility that other vehicles do not have on just where you can take it.
