The extra gears probably do help. I have a Gear Vendors overdrive in my old Dodge Cummins and 3rd+OD is a great pulling gear th struck didn’t originally have.
But I also think ALL of this is ridiculous! When you have a 30,000 pound trailer, you’re in big-truck territory. Not pickup truck territory. And you need a CDL.
My 385 (Pete) made 378 at the wheels on a dyno. It can run at full throttle indefinitely, uphill under a load and the EGT doesn’t get over 700.
That’s what you need to pull huge weight up mountain s
Trucks percentage of overall load is no more and more likely less than a Semi.
Your 4 speed auto is not a great example as there is a huge gap between 3rd and 4th. The modern 6 speed auto is very evenly spaced.
