My dad had a 2008 (I think, somewhere around that vintage) and it was the biggest piece of cr@p he ever owned. It was the 4L with 4WD. It broke down constantly. Most of his driving was around town (but not city driving) and he was lucky to get 15 mpg. Also, no factory tow package, at least not on his truck.
I had an 06 GMC Envoy that I towed a 3500# tt with. Body on frame SUV, 4WD, and I think they all came with a factory tow package. It had a very torquey straight 6 that pulled the tt with ease. Yeah, it had some nickel and dime types of issues, but with you tube it was all diy repairs.
They’re still around and relatively cheap.
