A contractor working on a Hospital project has a 2014 Super Duty F350 and is really impressed with it's towing ability... he has a special built tag trailer rated at 18k and will tow anything from multiple scissor lifts to mini excavators.
One of the guys that works for him spun the rear truck tires on dry pavement because he didn't realize the power is has when leaving from a stop light near the shop... the regular Diesel he drives takes putting your foot into it to get everything moving...
Several of the guys have 2006 F250 Diesels and are very pleased with them... for what it is worth.
The modern pu diesels run 800+ ft/lbs Tq. Of those, I've driven the 6.7L.
BIG Fun
