I need to tow 14k lbs with a 5.4l... Equipment trailer with mini ex. No way in hell I'm going to be able to get a diesel soon but that's the eventual goal. I have a 1999 F350 SD with a 5.4 triton, flatbed, air rear suspension, and a pretty sketchy looking hitch.

I'm in the countryside so I'm not too worried about speed, I can go 50 the whole way fine, I just need to know what to do to make it safe. Total distance ~60 miles one way 6-8 times a year until I can manage to get a better truck.

 

Pray?

That’s almost 2X the rated towing capacity from what I’m seeing.

Taking it slow doesn’t matter beyond a certain point as the truck still generates heat that need to be shed. None of the 5.4 driveline is rated for that.
