D100 Pickup question for you:

Granny low can also be used and appreciated if starting from a stop on a steep hill, pulling someone out of a ditch, if stuck in mud or another slippery surface, etc.

Mine with bald tires will move on wet grass up a steep grade in low easy, 2nd is a waste of time for me in that situation.

(painting the wheels now for new tires before Spring though)
