No 4wd, I am too cheap. 2001 Sierra with new General AT2's, locking diff, and 400 lbs of Anthracite in the back. Picked my daughter up from work on Thursday as the storm was building. Told her Anthracite was getting us home, she laughed. We came upon a steep hill, and I told her "Black Rocks Don't Fail Me Now", her response, "Dad you are such a Redneck. Do Rednecks burn Anthracite?
The Sierra is so much more sure footed in snow than all my old S trucks, S10's and Sonoma. They to where 2WD and I was a field tech driving 40,000 miles per year, in all kinds of weather, just driving smart. All local travel now less than 8000 miles per year.
