There's a little more to snow wheelin than just sitting in the warm cab of your rig. Snow sliding is like body surfing in the snow. To have perfect form, both hands must be straight up and both feet straight out. Getting down is the easy part
I wish I could find the picture of you falling down the hill in a few feet of snow with the camera up in the air, IIRC it was the only thing that was not covered in snow at the end....
