Thought I would follow up on my post regarding my 2014 Silverado (I can't believe its 6 months since I purchased and now finally used my camper). I am a first time Rv'r havng never towed anything more than a utility trailer, so this was a real first time experience for me and my wife. We towed the camper up to Lake Winnipesaukee with no issues except for a few gusts of wind which really can be nerve wracking, especially for my co-pilot who became extremely nervous. Some of the grades were pretty steep but it seemed to get up there fine. Downhills were also handled very well, the truck has a hill descent control system which worked very well.
I averaged about 9 miles per gallon, which was lower than I wanted but everyone I spoke with seemed to concur that sounded about right.
So, all in all, a pretty great experience.
Thanks to all who responded previously to my questions.
