A lot of duallys out there but the chevy does not make a 1 ton tuck only 1/2 ton trucks,
Only Ford and Dodge make a 1 ton Dually
Anything with a IFS front end is a 1/2 ton LOL,
What i like about the Ford is that the front end is so solid, I have done a Full Dig on the front end with 38'' tires on my dually never broke any parts, the lift is from Zone, under $1000 for a full lift with all steering components, the truck drive like new one finger no twitchy on pavement,
Best part about the ford Front end is the front Lock-Out hubs, Same hubs they have used for 25 years,
True 2wd, the front end completely unlocks, no front axle components are moving, the Chevy and Dodge have the front axle always turning, that does not work for me,
The 6.7 is a Solid Motor, I only have 160,000 miles on mine no issues, at 140,000 miles added the Banks adjustable tuner and pedal commander, truck has been solid,
Only major issue i have had is the Sun Roof has broken the plastic track twice, the sunroof has been a bad design on the Fords, so i just do not use the sunroof anymore.
