247,000 mi on the ol' 97. Bought it from a friend who used it to pull a five horse slant load for the first 125,000 mi. He was pulling over the Chesapeake Bay Bridge and blew a freeze plug, and started to overheat. Odometer was on about 95,000 mi (still under 100,000 mi warranty) so he floored it and smoked the motor. Cummins replaced everything back to the transmission free. So I've got 246k on the truck and transmission and about 150k on the motor. Not even broke in yet! There's a lot of small things that start to go wrong with THE TRUCK at that mileage, but I'd rather keep replacing everything with high performance parts than spend even more on payments. But I wouldn't even hesitate to take the ol girl across the country (except forthe price of diesel fuel).
