Crikey! Yeah, I'd fix that too. Pity he didn't know much about diesels, they're way simpler than gassers and it likely just needed the pump adjusted. Before it was "squished" our M1028 made it from Kansas City to St. Louis running about 70MPH and averaged 24MPG. And that was with the stock 3-speed TH400 automatic.
Gotcha. I'm going to hold off on the turbo for a while as I was duly impressed with the M1028's get-up-and-go abilities. Definitely will be on the hunt for the 5-speed manual so we'll have to compare notes whenever I get to that point. Right now my focus is putting a flatbed on the Mack and overhauling the brake lines on the M35A2 since it likes to blow a line every time I want to stop on asphalt.
