How heavy of a pack can you carry?
People always seem to struggle with understanding towing capacities, legality aside.
Just because something is rated to tow 12,000 lbs doesn’t mean it will do it up a 10% grade at 10,000 ft in the dead of summer, day after day, with no loss of performance or increased stress/wear.
For difficult conditions or regular use, I wouldn’t go over 70% of the rated capacity.
Power has almost zero contribution to towing ability. Wheelbase, weight, and gearing are far more important. There are a bunch of F-650’s out there with 180 or 220 hp, it’s just used by manufactures to drive sales.
A new F-150 is rated to tow more than one of my old trucks, a 2001 F-250 crew cab long bed with the 7.3L and 6 speed manual. With an exhaust brake, it was completely stress free towing 22,000 lbs on a gooseneck.
A truck that weighs 1,500 lbs less with a 20” shorter wheelbase and a taller final drive ratio isn’t going to pull better than that, no matter what the company says.
