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 just find this to be an interesting question...with all the mods on your truck and fire power inside your rig that you list in your signature and you are asking about the function of the basic 'tow haul' feature...
Go figure.???
But, yes. Use the tow haul when you are towing. It changes the shift points, keeps the tranny cooler, and engages grade braking.
RV'ing...forget about mileage.
SORRY I didn't mention that the truck was bought the way I is. And I just happen to like fire arms and believe in my right to carry if I choose to.
