I purchased new, owned for 3 years (still own) so far, and use the truck daily. Towing a 8,000 # trailer is no problem, truck could handle more. Ride is a bit stiff, but solid and handling is very secure. The transmission, with the 6.0 gas engine works fine, no hunting and shifts are quick and solid. Reliability has been great, with 43K miles only have had to do routine maintenance. The paint and finish are holding up very well, looks new after a wash. No issues so far, I would recommend this truck - but know that gas mileage is not great - 18/19 highway, 16 average overall.
I bought the truck brand new from a local Chevy dealer. The truck is only 1.5 years old and it has 37,000 miles on it. So far, the only time I took it to the shop was the to get the free oil changes and tire rotations. The fuel mileage I get: average highway traveling 65 mph is 22 mpg. Average highway traveling 75 to 80 mph is 18.5 mpg. I live in the southwestern part of PA so, traveling through the mountains I average 15 mpg.
It is the most comfortable truck I've ever driven. I drove it to Colorado 27 hrs straight through. My back and legs felt fine at the end of the trip.
As far as the power it has; I occasionally pull an 8,000 pound travel trailer and at times I forget is behind the truck. One of the features I absolutely love wether I'm towing or going down the mountain is the engine brake. You cannot go wrong with this truck. At this point, I only have praise for this truck. After 75,000 I will update this post. The only bad thing and I'm sure I'm not the only person who feels this way, THE DEF FlUID IS A PAIN IN THE ASS!!!!!!!!!!!!!
I only purchased this 5 weeks ago and it is winter. So I can't tell you a lot. It has power for 6.0L. I purchased the 2500 instead of 1500, because I just bought a 37' 5th wheel, which I will not be able to for 3 months or that warm weather arrives. So the gas mileage is only 12.3 right now. The ride is pretty sift. Lacks inside floor storage need to add plastic under rear seat storage. Don't like the fake ram air on hood.
acceleration, the solid feel, heated seats,
I wish they would have added a rear sliding window, outside rear view mirrors that were powered instead of manual so you could drive into garage.
