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.

I read it on here before and since then have followed this advice; "Whenever I haul or tow something, the tow/haul button is used."
Before I read this I too was wondering if I had enough cargo or weight in the truck to engage the option. There's no guessing anymore.
