Chevy has done a great job of combining comfort and usable power into one vehicle. I use my 3500 to tow a 35 foot fiver through mountain areas with no problems. the Allison tranny is great for hauls done or up long grades.
By far my favorite feature is the Allison Transmission.
The interior storage is pretty limited if you spend a lot of road travel time and have maps, guidebooks, etc.
