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.

You should probably use the tow/haul button when you tow/haul something. Also you might want to put the transmission in D when you want to move forward.
