i bet they're slow though aint they?
are they in 4wd the whole time? it would seem to me that they would have to be.
Those would be great in deep snow. I went on a snow run a couple years ago with my CJ7 with locked front and rear axles and got stuck probably a dozen times. We spent all day and only went a couple miles. The snow was almost waist deep on me and we had a little thaw and then a refreeze over the top so when our tires would break through you couldn't get back on top. If you stepped out of your Jeep you'd stay right on top of the snow like it was cement and you'd be looking down at your Jeep.
OMG I WANT IT!!!!!
