NO WAY the miles and hours match up on this. These things were geared to pull 40-60,000 pounds and max out at 20-25 mph. Even at 25 mph CONSTANT speed it should have over 500 hours. On top of that, these things got a TON of idle time sitting on the flight line. They were used primarily for Aerospace Ground Equipment like heaters, generators, and maintenance gear, and ended up as the only place to warm up... Being this old, it might have come from a Guard or Reserve base and be in decent shape, but usually they were pretty far gone.

The hour meter records the engine running time so, when it's sitting with the engine running, it's recording time but not miles.

See the "AMMO" sticker on the back window? We use them to haul trailers back and forth to/from the flightline and in the bomb dump. They don't get near the use in the bomb dump as they do when used exclusively for aircraft support.
Having said that, just because it was last used in the bomb dump doesn't mean it spent all of its life there.

The ackerman wasn't changed for the shorter wheelbase. These things eat front tires like crazy.
A neutral drop will create wheelies

No doubt, and ALL of them were rode hard...regardless of which unit they were assigned to.

So what's this low mile Cummins and all the junk that comes with it worth?

Ever work on a Jeep bobtail with the Nissan forklift diesel? First the AGE guys figured out they could remove the steering stops on the front axle to turn sharper. So much flex that they'd get cracks cross the back of the cab from body mount to body mount; TCTO to inspect and repair, plus reinstall the stops and weld them in place. Then they found out that the Jeeps didn't have a super-high rear axle ratio, just a transfer case with no shifter and a plate to lock it in low range. With one 3/8" bolt holding the plate on. Pull the bolt off, use the plate to shift it into "high" and they'd run 50+ mph. They rolled one on midnights at Mildenhall...
