K9, I pulled mine with a 91 Dodge 3/4 Cummins/auto, pulled it fine but it was the heaviest thing I have pulled to date. Its definitely heavier than the 89 dodge dually cummins I pulled a while back, and that was using a much heavier trailer I borrowed. I estimated that load at 8500lbs, 3000 for the trailer and 5500 for the truck. My 52 has the 3-71 and the two speed with 5.57 high range. It was a number 4 wheelbase but was shortened to about 142" wheelbase and used as a yard spotter.
