I put it in "Tow Haul" set the cruise about 60-62 mph (2,000 rpm w/ 4:10 rears) and let her run. The truck will do what it feels is right. Towing 12,000# and normally it will only drop 1 gear to go up a hill. If it's in tow haul the computer will protect the engine and transmission.
no tow haul in 2001
On flat to hill run in 4th. When you start climbing drop to third. A pyrometer will help you determining where your engine rpm's should be.
