Truck-kun would probably like the ability to ditch the 70-75mph governor, delete the DEF system, have working A/C, off-road tires with 6x6 diff locks, go under 11'8" (now 12'4") bridges, a conventional cab, spacious yards, generous docks, cheaper diesel, less gouging at truck stops, lot lizards that somewhat resemble humans (and haven't collected every STD twice), non-kamikaze drivers, and a few more days off. Or, maybe that's just me...
