6.4 Hemi Trucks

I have a 2014 6.4 Hemi 2500 long box crew cab 4x4 to pull my dart. went to buy a diesel but the new emission on the new model scared the hell out of me. going to the black hills in south Dakota it got the best of 14.9 mpg with the cruse control on and plenty of power and that was on low grade gasoline. Has 12k miles on her and no problems at all except recall notices and the 0-40 grade Syn motor oil. Oh, empty it gets up to 17 mpg:D
