I just returned from a trip to San Clemente SB and got 11.5 mpg towing (@ 55mph/max speed limit in CA when towing). I ran into slow traffic (15-20mph) for a good half hour or so. Still think I could get better mileage using the cruise control.
Went to Las Vegas for a turnaround trip (502 miles) and with two of us in the truck got an average of a little over 21 mpg (not towing). The truck held up nicely in the strong winds coming home.

That sounds about right. I'll admit, I drive like an a-hole (not while towing though) simply because I enjoy the power of the Tundra

Most people drive faster than me & many of them have tickets to prove it. 
The 4-1/2 hour drive to Las Vegas actually took 5 hours (stopped for a quick lunch). I know several people that have made the drive in the 3 hour range.

Don't count on the Tundra's cruise control giving you better mpg. I drop about 1 mpg using cruise in my 2008 DC Tundra. I will use it occasionally if I see a long mild down hill grade just to reposition the foot for a bit. I don't think the Tundra is properly mapped for cruise control and towing. I can soft foot it and keep it from downshifting for quite a while.

Not just the Tundra, I see the same thing on my F150. I try to leave my tranny in OD as much as possible, but cruise control gets it shifting where my foot does not. I might back off some on the small hills, where my cruise control would give the engine gas, requiring a downshift. I sometimes will cut off OD, and use cruise control to get a little break, but I don't like the fuel mileage with that combination.
The Blue Ridge Foothills, and Piedmont sections of VA. are rolling hills.

EXACTLY! This is the way I tow in hilly areas too. Makes a world of difference in towing mileage. The cruise control on my Ford would let it drag down a couple of MPH and then "over react" by exceeding my setting by 2 to 3 MPH at the top of the hill; and of course it would downshift. I'm betting that that is common across all brands?

Same with my 2006 Chev. When towing and using cruise, it down shifts 2 gears right away. Manually, I can keep it out of the lower gear, and it seems to do about 1 mpg better. Wayne
