Nice choice 2Bears,
We have several F-350 6.7L at work. The trucks in our yard are labeled to handle 8000 lbs. load in the dump bed; and, 20,000 lb. trailers is the heaviest trailers we hook up to to the F-350's. The trucks get up to traffic speed at a reasonable time, stops the load great, and I love the performance of the automatic transmission shifting (up & down) while in Tow/Haul mode. Truck doesn't feel like it gets pushed around by the loads.
I'm sure you'll like the engine/transmission performance from your F-250.
