WELL we have been through this similar topic before:
CAT--most durable
FORD, was never a big fan until the Super Duty series (WE HAVE PUT THIS TO THE TEST)
We have been all over the country & have had this so overloaded but it keeps on running trouble free
ALMOST 300,000 HARSH MILES
STATS DON'T LIE
It has been in every type of Industrial environment (coal mining (almost every state that has them), steel mills, coke plants, lime mines, iron mines (Missouri), nickel mines (Canada), gold mines (Colorado), silver mines, through flooded rivers and the list keeps going)
We have weighed in up to
28,000lbs with our truck & trailer loaded on a 3/4 ton truck
Below is a picture taken Friday we travelled 1200 miles in 2 days to an underground lime mine (weighed in at 25,000lbs)
We have only replaced an alternator, a cam position sensor (minor), ball joints
FORD BUILT A DAMN GOOD TRUCK THIS TIME
My other friend that travels the country repairing industrial locomotives has over 500,000 (HALF A MILLION MILES) on his Super Duty
DODGE--Cummins is great but my friend spends all of his time repairing the truck around the engine & has only pulled (2) major loads that I know of. He will not even drve it out of state because he is worried something will break on it.
CHEVY / GM-- Well we have owned them & bent the frames END OF STORY
