I towed a 29' 5500# trailer with a 2011 Avy LTZ. I was usually over on payload by one or two hundred pounds as payload for my truck was 1,060# or something like that. I had the six speed trans and I swapped in a 3.73 gear. Power wasn't a problem in flat Florida but the towing experience wasn't the best.
And yet the OP's Av has the older wide ratio 4-speed, as does my own Av and as did my previous Silverado ... even a 3.73 coupled to that 4-spd won't make for a pleasant towing experience with a trailer as heavy & long as he's intending to tow with this truck. :( Could it be equipped with a 4.10? ... possibly, but I doubt it. ;)
