    I guess it all depends on your engine's power levels, your tranny, the weight on your wagon and the grade. Another thing I would factor in is the particular clutch you have. The last thing any of us want to see is a truck on a 2 lane in Pennsylvania halfway up a 10% or steeper grade with his hazards on because he glazed over his clutch.

    Or even worse, the clutch held and the driveshaft twisted like a pretzel.

    Had a company truck that was set up so bad that it never successfully made a trip through the Rockies (you all see how beancounters set their trucks up....cutting the power more than .10 percent from the manufacturers specs), and I had to get towed out of the Rockies back to Denver. The dragon wagon hooked up to my truck, removed the driveshaft, stuck her in low and pulled. She never bucked or jerked, smooth as running on flat ground. With the weight of my truck, plus a fully dressed dragon wagon, I figured the whole load had to be over 105-110,000 lbs.

    We had a tri drive that a bunch of drivers kept ripping the driveshaft out when trying to start off. The power was just incredible. You had to start off in the low gears and go easy...because if you didn't, the engine would destroy the driveshaft or start snapping axles.

    You stop on a hill if traffic stops in front of you.

    Is using your trailer brake an option for staring out on a hill?? using it to hold you from rolling back till the clutch starts grabbing??

    Use your foot brake...in a truck you never use the throttle and clutch at the same time starting out, just keep your foot on the brake and ease out the clutch until it starts pulling you up the hill, if it stalls on you, choose a lower gear.
