I am operating a 2016 F350 Dually 4x4. The as built weight capacity rating is 7450. The Eagle Cap 1165 I have is showing an as built dry weight of 4800.
Loaded with a half tank of water I weighed 60 pounds under GVWR.
The upgrades include Air Lift 7500 airbags, Stable Loads, Rancho 9000.
These upgrades don’t change the load capacity for legal purposes, but do offer a more stable/ comfortable ride.
I pull a boat routinely and will flat pull a small SUV when that time comes.
The giant worry to be considered is liability if you cause a catastrophic accident.
Otherwise I am very comfortable with my setup.
Respectfully,
Kent
