bshpilot & Horsedoc - beg to differ - It gets about the same fuel mileage as a typical large Class C with gas engine and automatic transmission, maybe better: 8-10 mpg. It has a specified top speed of 75mph, so it can comfortably cruise at 65mph. The motor puts out 960 ft-lb torque.
It also has some features neither of your vehicles have: 4WD, low range, 9spd synchro manual transmission (Allison optional), air locking differentials, central tire inflation, 14.00R20 (49.5") or 16.00R20 (53") tires.
Obviously not designed for the interstate cruising you guys appear to be fond of, but better for some other environments.
