I've found that my truck pulls way better without using 6th gear. I used to just let it do its thing using all 6, but towing seems a little easier using just 1-5. Also, I noticed a slight mpg increase. With 4 horses on... from 9.3 to 9.8 and with the tack trailer from 8.5 to 9. (thats highway/turnpike towing with cruise on at 68mph, both goosenecks) Just thought I'd share!

 

I'm guessing 3.73 rear gear?

 

Yes, you guesses correctly. That's all that was on the lot and I needed the truck right then and there!

 

What weights are we looking at? Is you truck 4x4 Crew Cab and Long Bed?

 

Is that common go get better gas mileage towing in 5th gars vs 6th?

 

It's a reg cab long bed 4x4 (FX4)
