Well we made it thru without losing power. The only thing I wasn't prepared for was having my truck tires frozen to the ground. Being a two wheel drive the back wheels are sitting on 1" of ice and the front wheels are packe in ice.
The back wheels spin real nice and smooth.

My neighbor's 4 wheel drive is also frozen in. His left front and right rear spin freely'

I have packed salt around the tires trying to melt the ice.
