I agree with keeping the rpms down. my 4x4 with 3.73 gears will get 18-19 not towing, but here in the mid atlantic towing where I go, you can't keep it that low rpm (or at least I don't). There are alot of hills I pull at 2900+ rpm in 5th gear. That equates to about 8.5 mpg. 9 if you average a whole trip.
