I really like mine! it's got about 6500 miles on it and most of those have been pulling a 22 ft horse trailer loaded. the shift on demand is nice for when pulling and when you come into town the truck wants to lug a bit. but once you knock it back to 5th it just rolls right along!

things are good w/ the 6.7 and the new trans!

Mine has only 2300 on it only had it about 5 days. So far so good. She feels strong and tranny works great shift on the fly is nice. Factory exhaust brake seems to be working correctly. Lookin for upgrades now. It gets my vote for a pretty good truck. I cant wait to hook her up

I've got about 12K on mine now, and I've been happy with it. I haven't worked it alot, but the tow/haul mode when I did worked great, thign downshifts perfect and with the exhaust brake the brakes aren't getting worked hardly at all, shifts are nice and firm too, mine shifts pretty damn hard for a factory tranny. A welcome change to the automatic's I have had in gas dodge pickup's over the years, this thing shifts you know it, no marshmellow tranny anymore

Mine has 72,000+ kms on it. This is the best tow rig that I have ever owned. I love the Tow/Haul mode and the engine brake. I tow an 8,000 lb travel trailer, usually with 1,000 lbs in the box. Locked on cruise at 120 kph, I'm getting 13 to 15 mpg imperial, calculated. Driving it and pulling is effortless. Empty locked on cruise at the same speed and on the same highway it gets 20 to 21 mpg. The truck is stock except for a gutted intake tube, a drop in aFe filter, a 4" hole in the bottom of the stock intake box and the EGR is unplugged.
