i own neither but i have an opinion. first, the 4.8 V8 rocks, but that doesn't enter into this discussion.

typically, a diesel engine will deliver more torque, greater towing capabilities and longer in-service duration. they are somewhat more expensive to maintain as they do require steadfast resolution to maintenance intervals to perform properly. oil and fuel purity being the keys to diesel longevity. basically, change the filters and change the oil.

diesels run on oil pressure, so clean oil is key.

i have a diesel F350. wouldn't trade it for any other pick-up made.

personally, i've been jonesing for a 335D. sadly, the budget will not permit it.
