I have a 01/. 5 3500 dually with an EZ installed. Just bought a new chrysler 300M. Just came back from Lake Tahoe on hwy. 50, twisty, turny, up down road. I SWEAR my 3500 will eat the 300M, up down cornering etc. I don't know what to think about that. My wife says I'm crazy, and that the car rides better, takes the turns better, etc. I tried to tell her that's because we're going SLOWER but she won't believe me. Hard to believe the truck would be that much better under these conditions,, but it's true. Only thing I can figure is the truck has more low end grunt, and that maybe if I had the car on the pipe, 5000 RPM plus it would do better, but? I'm telling you, diesel trucks kick serious BUTT! I guess I'll let her drive the car,,, I'll stick with my 3500!!!
