I took my Z71 to mammoth over the weekend in the middle of a snow storm/blizzard warning and got the chance to test its off road capabilities for a few days. I must say it performed excellent. In a chain controlled 35mph limit, i was cruising at 50mph without any issues. At one point i had to swerve around a 4-runner which was sliding to avoid a collision. The tahoe handled withou ever losing traction...i was very impressed and am loving my z71 just a little bit more after the trip....
