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 purchased my first travel trailer the weekend before last. I towed it home over the Willamette pass here in Oregon. Turning the tow/haul on was very different than with it off. Especially going downhill. The Tow/Haul on my 2006 Crew Cab long box Duramax man handled the trailer. The engine was in charge and pushed around the trailer instead of the trailer pushing around the truck! I was extremely impressed. I have towed with a manual transmission before and the tow/haul mode felt like it did much more than just engine breaking. Coming down hill what ever speed I let my foot off the accelerator the truck just kept that speed. It didn't slow and it didn't accelerate. To do this with a manual transmission requires constantly modulating the accelerator.
On another note this was the first time my truck has ever actually worked since I have owned it! It was a different feeling to have the Duramax do anything other than move me along while basically just idling. (I have had my Duramax just about a year). I really love the power and the controlled engine breaking!
