I have put about 800 miles on the Super Duty and am still testing it out. I installed the exhaust system at 650 miles and loaded my first mild test tune at 750 miles. So I am looking for something to haul! Well a buddy needed some dirt work done so I hook on to a Babcat skid steer tractor. We pulled it forward on the trailer and it still didn't touch the laod springs. It felt like I had a riding lawn mower back there, lol. This loader is suppose to be around 6K lbs plus trailer, compared to towing a stock Lightning which is 4800lbs plus trailer. I need to find something larger to pull next .
