"Bought my Dually new in 2007. Full time RVer pulling a 14,500# 5th Whl and 6x12 1400# trailer. After 72,000 miles it is still trouble free except for a couple of minor recalls. Getting 10-12 mpg when hauling at 55mph and 16-20mpg unloaded with the diesel and Allison 6-spd both of which are flawless. Had a 2004 previously which was real good but this 2007 is way better. Will buy another Chev if this one ever wears out. Resale value is unbelieveable."
"I purchased this truck new in 2007: the main purpose to pull a 32 ft. 5th wheel trailer. It has exceeded all my expectations in towing, especially in the mountains of colarado and the 6 speed allison transmission is so much better than a standard. After 3 years and 30,000 miles, I am totally satisfied with the truck and would recommend it to anyone who is looking for a serious man truck!!"
