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.
Sitting up high gives me a great field of vision ahead, the power plant is amazing, the interior is nothing like anything I've had before especially the ac seats. Five adults can go to the country club in style. It is a head turner for sure. I added a Lear Topper for storage security and it added more styling points with friends.
Its great if you need something this big. I think its one of the best trucks on the market. Ford F350 is better comfort wise, however it costs so much more.
