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.
