Hey there,
We have about 8" of show and ice on the ground and the old truck pulled through like a champ. I guess all the snow in the back puts a little more weight on the back wheels. I did find out that I seem to have semi-slip differencial. The new tires on the front helped too. I used to have the old bias-ply on the front that were slick as deer guts on a door ****. I can now steer Yippee!
Hope everyone's travels are safe! Happy Holidays!
Scott
