'O4 was the crossover year. Some shifters say tow/haul while the function is still O/D off. I'd leave it off (O/D on) unless you're in slow hilly roads making it shift too much. Won't hurt the Cummins to run 2500rpm though. My '98 12v 5sp/4.10 ran 2500rpm 70mph in 5th towing or not. Made for some long days listening to the shop vac under the hood but won't hurt a thing.
