John, my driveway gains 200 feet over 1/3 of a mile. I always climb and go back down in 4wd(you need that 4 wheel engine braking going downhill, especially with a load/trailer) and medium gear. My rears are loaded and most of the time I have a box on it and in 2wd it will climb, but they do spin a bit. I run at max rpm(DK40 is just under 2500). I also remember on my CK30, putting the rpm on the small red hash mark on the gauge(HST loves max rpm). High range ain't gonna cut it on a 10% grade with any HST that I have driven.
