I have owned three seperate Dodges and absolutely love the Cummins over the Powerstroke. I can say that since I currently own both. My wife drives a 2003 Excursion with a Powerstroke but the engine has had nothing but problems. I have replaced the alternator twice, injectors, powersteering pump, gear box, and the thing constantly leaks fuel. Other than the engine, the Ford is holding up in other areas. My current truck is a 07 Dodge 3/4 Ton with the 5.9L and has 126,000 miles. I don't really pay too much attention to fuel mileage b/c I need pullin power to transport heavy loads over the divide. That was until I started test driving the new Dodges. Wow! They are impressive for pulling power but boy do they drink down the fuel! The model I test drove averaged just over 10 around town and we hooked her up to my horse trailer and pulled her down the road a bit and averaged around 10 1/2 mpg. Plenty of power for sure and a really nice ride. Not so sure I am willing to eat the fuel costs at this point as the difference is very noticable from my old 'Red. Might wait until Cummins fine tunes the fuel efficiency a bit better. Other than that, I tend to notice that the Dodge front end tends to go to heck around 90,000 miles and the rest of the truck falls apart soon thereafter. The engine will last for a good 300,000 miles but the front end and suspension repairs will drive you to the bank. My wife's Fords always hold up much better with the exception of the engine.
For about 7 grand cheaper than the competition, the Ram Mega Cab with diesel has more room, better mpg, more power and more options than others of the same year... Jake brake standard, heated and cooled leather seats and steering wheel, gps, Sirius, 4x4, backup camera, tv/DVD - you name it. In town, with the 6.7L I'm getting 15.1 mpg. On the highway, commuting 104 miles daily, I get 21.9 mpg without towing and 14.1 when towing a 10,489 lb trailer. Ive been able to squeek out up to 22.4 mpg a couple times. I simply couldn't be more pleased with this truck- and for more than 25 years I've been a Chevy and Ford driver. I drove both before settling on the Dodge- I'm glad i did. 33k miles so far and not a lick of trouble.
Great Truck. Have had it for over 50K and not a lick of trouble. Unbelieveable MPG with a manual. Get a consistent 21.5 mpg around town and 20 on the highway. Even towing a large load have never posted less than 16.3 mpg. Power to spare in the hills of North Carolina. Super vehicle.
