it basically changes your transmissions shift points if i'm correct, to shift at a higher rpm, so your truck will be less fuel efficient with it on. if anybody else with more in depth knowledge on this would like to chime in that would be great

To add to what has been mentioned above, is information, regarding the Features of the Tow/Haul, and How and/or When it should be Used,
The Purpose of the Tow/Haul Mode is to:
***Reduce the frequency and improve the predictability of Transmission shifts when pulling a heavy trailer or a large or heavy load.
***Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded.
***Improve control of vehicle speed while requiring less throttle pedal activity when pulling a heavy trailer or a large or heavy load.
Automatic Transmission equipped vehicles are provided with a button at the end of the shift lever which when pressed enables Tow/Haul.
***When the button is pressed, the Tow/Haul has been selected. Tow/haul may be turned off by pressing the button again, at which time the indicator light on the instrument panel will turn off.
***The Vehicle will automatically turn off Tow/Haul every time it is started.
***Tow/Haul is designed to be Most Effective when the Vehicle and Trailer Combined Weight is at least 75% of the Vehicle’s Gross Combined Weight Rating (GCWR).
Tow/Haul Is Most Useful Under The Following Driving Conditions:
***When pulling a heavy trailer or a large or heavy load through rolling terrain.
***When pulling a heavy trailer or a large or heavy load in stop and go traffic.
***When pulling a heavy trailer or a large or heavy load in busy parking lots where improved low speed control of the vehicle is desired.
***Operating the Vehicle in Tow/Haul when lightly loaded or with no trailer at all will not cause damage.
***However, there is No Benefit to the Selection of Tow/Haul when the Vehicle is unloaded.
***Such a Selection when unloaded may Result in Unpleasant Engine and Transmission driving characteristics and Reduced Fuel Economy.
***Tow/Haul is Recommended only when pulling a heavy trailer or a large or heavy load. __________________

I have that tow haul button also, and I love it when there is a load in the bed or I am pulling a trailer. It is nice to know the specifics about it though.

About half the miles I put on my truck (2001 Z71) are towing a car. I use my tow/haul mode when I am towing a car, but when towing the empty trailer (about 1200lbs) I find that it limits it's desire to use overdrive. I find that it causes firmer shifts, changes the shift points, and specifically limits how often it shifts in and out of overdrive when driving in the hills here in western NC. So....pretty much what 99'HEARTBEAT said, but that gives you an idea of how much of a load it takes to be effective.Everyone should own a Ford once in their life....how else can you truly appreciate a Chevy?
