Ford is killing GM in the HD gasser lineup. Not only with a bigger stronger motor, but have the 10 speed tranny, and in the 250 a choice between 3.55 and 4.30 rear ends. In the 350 it is 3.73, and 4.30.
I’ve been driving my 6.0 for 18 years and it has been great, but decided to wait on the 2020’s to get a bigger engine, but was disappointed with the 6spd, so I’ve decided to wait a little longer and see what they do for 2022. If they still have the 6spd and no axle ratio options, I will go with the either the Ram or the Ford. I’m planning on going to about a 12k lb 5th wheel in a couple of years, and while the Chevy would pull it, the For and Ram will do it better.
