Hello....anyone have experience with 4x4 usage? I have a 64 k10. I'm expecting ill need the 4 wheel drive with all the snow we received. What is the protocol when driving in 4 wheel drive? If I'm running errands and the roads are bad, can I drive the truck in 4x4? is there a speed limit that I should not exceed while in 4 wheel drive? Any rules of the road would be appreciated. Everything is original on my truck and in working order so I'm concerned that I can damage the mechanics if I drive it more than to get out of my driveway. Thank John
