Towing 5K # with a gasser

Our 13 Explorer weighs 5k with 4 bikes and a kayak. We tow it with our 2012 V-10. It did great coming out of Denver up I70. IIRC we were at around 45mph or so going up. You will want it to rev as that where it makes it’s power, don’t be afraid of 4500 rpm even close to 5k is t out of the question. It was 90 degrees leaving Denver and the engine temp never exceeded 210 during the climb. We got off at I70 at US 40 and went up and over Berthoud Pass at 11,300ft! I would do it again.

Since then I have installed a tune from 5 star and the performance is much better.
