As above, I tow in OD until the transmission starts "hunting" on a hill, then I hit the button to lock out OD. We have some significant hills that I pull, the worst is an 8% 4-mile long grade. I hit it as hard as I can legally drive, then lock out OD when the transmission downshifts.
When speed drops, and it automatically downshifts to 2nd, I pull the lever down to second also, back off the throttle, and ride to the top.
Downhill on that section, I hit the top of the mountain as slow as possible, pull it down into 2nd, and use the brakes to keep my speed below about 45 mph. I'll let it run up to 45 mph, then brake hard to drop it to around 40 mph, let the brakes cool as speed picks up, and repeat.
