i`m overall quite happy with my 6.2 and reasonably happy towing a 4500 pound, 7x14 cargo trailer with it (several 1500km days). I don't think a could say the same for the 5.3, having previously towed other trailers with the 5.3 in a Sierra. That said, I do miss my 2500 Sierra with the 6.6 diesel on the big towing days.

I have a 6.2 in my 2021 Suburban and tow a 26-foot 5,500 lb. travel trailer. It tows fantastic. I have no problem using premium as all of our vehicles require premium, 2017 Camaro SS and my 1976 Pontiac Firebird. I like diesels but worry about all of the emissions devices and their longevity and diesel price is close to premium plus DEF.

Many have said the DEF consumption of the 3L duramax is pretty high under towing loads, just something to consider. I love towing w/ the 6.2. Had 5.3 in all my previous rides. Never going back.
