I think its funny that everyone with evos or subis with snow tires thinks they cant get stuck. Sure if you stay on the beaten trail you wont get stuck but venture into some deeper chunkier packed 15"+ stuff and you will get stuck.
And you will probably rip off your under trays doing so.
A 4x4 truck with good tires is the best bet due to its lift. Anything that drags in the snow or gets its underbody on top of the snow is going to get stuck.
