Tow haul button
I have a 04.5 duramax 3500 and I'm not sure when to use the tow/haul button on my gear shift also using this will it help my MPG? Thanks.

With a 35ft MH with toad, I like the feel speeding up and slowing. When the toad is on I am in Tow/Haul Mode. See no real difference in gas mileage, but I knew it was not an Economy car when I bought it. I have a V/10 Gas engine.
