Bishops,
Does your truck have the 4spd tranny? Can't remember when they went to the 6spd, may have been '09.
Biggest issue you will run into is payload for the hitch weight. Depending on how much you load in the bed of the truck, and what your family weighs total.
I had a '10-1500 ccsb 4x4 5.3/6spd/3.42 and never felt I had to have more power pulling our old ~6500lb tt or our new(er) ~7300lb tt. Issue was PAYLOAD! We did have a cab high topper which will eat up 200lbs, but subtract that and we were right at gvwr (over w/ topper by up to ~200lbs), and right at the rar.
How many do you need room for in the trailer?
