I ran it through the paces. There and back 7 miles each way at 3500 RPMs. Then four of the 2.5 mile lengths of our slough. 1 with no ballast at 28mph, 1 with 1180lbs at 21.5mph, and 2 at 10mph with 3000+ lbs of ballast. No issues and the fuel consumption seemed better than it's been lately. So hopefully I'm finally in good shape.
