In the City I have found that I need to push the Tow/Haul button in when I travel at under 42 M.P.H. This increases my gas mileage by 1.5 per gallon. I.E. 14.5 my normal with overdrive in, 13 M.P.G.

In summary:

I won't do 55, & I have tried it, the highway mileage is worse for my truck!
I agree (same truck here), 65 works out pretty good, if you to 70-75 it drops a few mpg and 85 it probably drops at least 3 mpg. I can't really drive 65 though I do try sometimes. But people need to realize its not all "the speed you are driving", its gear ratio, weight, aerodynamics, tire drag, blablaa etc...
