Tow haul mode
I am sure this has been discussed before, but who uses it and how? I have a 1 ton diesel dually and will be towing a 5500 lb (dry) trailer. I am assuming it will lower fuel economy? Am I correct in as...

As noted the tow/haul alters the shift points to reduce "hunting" and also to keep the rpms up before it shifts to prevent lugging.
On mine I turn on tow/haul as soon as I hook up and it stays on until I unhook. But that is with a 35' 5er. With your lighter trailer and the dually it probably will not make much, if any, difference in your towing.
