Cant help with that, I'm afraid. Sounds like a bad idea to me: at some stage you are going to have to put your wheels/skids on the ground, and when you do, you are going to need to be looking outside with a decent reference, so you can tell that you are not sinking one one side. You dont know whats under the snow - could be a tree, a rock, a soft drift, whatever. For the same reason, you are best to do this multi-crew, so someone can look out on the left and see what sticks out underneath the cab on that side when you blow the dust/snow away.
