Look at the Final Drive Ratio charts and notice the great benefit in gear-splitting with the GEAR VENDORS. When you are climbing grades you will have a gear between 2nd/3rd and 3rd/4th that is ideal for keeping the engine in the power and the torque multiplication up. Look at the horsepower and torque curves and notice that by keeping the engine in the power you will gain 50+ horsepower and 60+ lb ft. of torque without any modifications to the engine.
The more heavily you are loaded the more you need the GEAR VENDORS and when you are heavy you would do best by not using 5th but instead 4th + GEAR VENDORS (4th-over). This will keep your transmission temperature as much as a 100 degrees cooler (extending transmission life) and instead puts the stress on the GEAR VENDORS planetary gearing which is much stronger.

When you are running empty (without the aerodynamic load of the trailer) you can use double overdrive (5th+Gear Vendors) and enjoy 22% lower engine rpm and better fuel mileage. At today's 75mp highway speeds and high fuel prices this is a feature that will pay for the overdrive. You will have a vehicle which performs better, cruises with low noise and great mpg, has all the right gearing to take better car of the engine, and is just a pleasure to drive, with an overdrive that pays for itself. If you have 3.54, 3.73, or 4.10 diffs - you just have to have a Gear Vendors Under/Overdrive. Expect 20% better mpg at the same cruise speeds you do now.
