I have a 2015 burb. 5.3 has great rear suspension with auto air bags, with stablizer bars towed a 29ft decent. Gas was insanely bad, to be expected. But really bad. 130,000km and front end is brutal, taking in for shocks/struts. Bouncing bad. But 4 kids and 2 dogs, love the 8 seats, and ltz loaded is nice. Was thinking about super charger cuz I'm stupid that way, but think I'll keep saving and drop a 6.1 in maybe.
I tow once a year 6500lbs. So not a deal breaker for me.
That's my opinion anyways.
