anyone have any experience with them. I love my new ram (first ram) Its great in every catagory but at 18-19 mpg its a good 3-4 behind a v8 chev. There talking close to 30. I know it wont have th snort a hemi has but ive got my car if i want to go fast. Just dont want one if its a total slug or isnt a good motor. Anyone know how theyve been holding up? Sure dont need a 3/4 ton truck or for that matter a 70k truck. But near 10mpg better is making sense to me.
