Hi Gang, My '06 Tacoma got 16mpg towing my M17 to the North Channel last June. It has the 4.0 L V-6 and a 5 speed auto. I kept it out of 5 gear. The truck never broke a sweat. Of couse, towing the M23 is a whole different story, I haven't tried that yet. Happy Thanksgiving fellow wrinkle boaters...... Bones
