I bought a 2006 6 cylinder 2WD 4Runner in March. This weekend I made my first twoing trip with my boat. It is about 4500 lbs per a scale at a landfill near Lake Lanier. I picked up the boat Sunday and took it to Lake Oconee - aobut 125 miles each way. I didn't fill up with gas yet to check mileage, so I don;t know how it did in that repsect. As far as ease of pull, I would say it did it better than my '01 Dodge Dakota Quad Cab with a 4.7L V-8. Mileage is far better - I'll post when I calculate it. I kept 65 MPH on the interstate. Coming back was 97-99 degrees. We really didn't get out on the lake as much as planned because it was just TOO hot! Overall - very happy with the T4R.
