250K on one set of tires?
Second set of replacement tires: original, first replacement, and second replacement: 0-miles, 120k miles, and, maybe, 250k miles.
Time will probably run out on me before miles (MICHELIN sez five years on tires is the end).
Acceleration on one of these is very impressive, if:
you're as old as me and remember work trucks of the 60's and 70's AND
especially when one considers the fuel mileage possible.
A 383 or 440-Dodge 250 with 3.55 gears could really move out and tow a nice trailer. But it was doing so at 7-8 mpg, where this truck does the same work at 15-plus.
The rule of thumb in towing is that 0-60 in twenty seconds is plenty. 22 is okay, 26 is hurting. 18 is pointless if it comes at the expense of fuel economy.
Same is true for mountain climbing. The sheeple get skeered if they slow down to 45 mph up the hill. Down the other side of the hill is all that matters. So they'll add tuners and other junk shortening the life of the rig first.
No free lunch in power tuning.
But there's no end to power in a CTD. Check this video:
