So. I went back to a ram and was just impressed with the towing capacity of the 15. I went with 3.42 gears and it turns around 1500 rpm at 70 mph. I loved the Toyota BUT the mpg towing and the small fuel tank was not cutting it. I could not head across state towing my boat without stopping for gas. I towed 3000 lbs yesterday with the 2500 and averaged 16 mpg.
