I'm looking to replace my current tow vehicle to pull a small camp trailer (<4000), so I'm looking at these 2014 - 19 units. I'm not that familiar with the 'newer' Chevys. I had an 06 a few years ago but it was getting up there in miles (286k), got something else, but now need a newer truck. Although my current trailer is fairly small, I may upgrade later, hence the search for something in the 8000# tow capacity range. Realistically, although I want something that can tow, the majority of actual miles will be unhitched, so I'm looking for something above 15 mpg with no trailer. So, although I know it's a subjective question, what are your favorite years in this series? With a 5.3L and 4x4, what are common issues? I've looked through these forums and although I see issues, I can't figure which ones are the most common for the above models. Please let me know if there's a specific thread or site that details the above. My searches have been not very fruitful. One thing I can't find is: is there an extended range fuel tank available in the 1500s? How common is it. Thanks for your help.
