I like to use low 1st to back up my driveway. There's a slight incline and I have to snake around whatever other cars, tractor, etc. are parked there at the time, which isn't always easy since my truck is regular issue, not bobbed. I always park the Deuce in the back near the house. Going at that slow speed allows me to stay out of trouble. I have the tarp on the truck now and depend 100% on the mirrors to see where I'm going. In low 1st, the truck moves without jerks - if I don't hit anything.
Every once in a while I use low to get to the main road just to shift through the gears in low.
