I just completed a 1,300 mile tow yesterday from SoCal to DFW, TX. I towed at 70 during the night and 75 during the day. YES my tires are rated for that speed. Including two 2 hour times stopping during the night having my high idle set to 1,000rpm to protect the engine and keep heat in the cab. My fills were to the top and hand calculated to between 7.5 and 8.0. Truck did not shut off during the 27 hour trip. Combined weight 33K.
