You'll probably get a lot of responses, there are a lot of Dodge owners on here. I've got a 2010 Dodge 2500, and there is no comparison between the Dodge & the Chevy I used to have. But to be fair, the Chevy had a gas engine. We were in CO this past summer, and the Dodge pulled the mountains like the her wasn't back there. I've got the exhaust brake on it, & LOVE it. While going down hill in tow/haul, hardly used the brakes, actually had to speed up sometimes! Also got the factory brake controller, and it works fine. Some people have had problems with theirs, but so far mine is working fine. I've got around 30,000 miles on it, and I'm getting around 22MPG on the road without the 5er, and around 12-14 with the 5er. All in all I'm very happy with it.
