Any of the half tons listed should pull the trailer with ease, assuming that they are properly set up with tow packages and WDHs. The 6.0l is a beast, but requires high test gas. I tow a 26' 7500# (8800# max) TT with my 2016 Sierra 1500, 5.3l, 3.42 gears with ease. I didn't skimp on the hitch and bought an Equal-I-zer WDH. The truck is as stable as can be and can be driven with one hand. I also have the stock P tires and run them at the recommended pressure of 35#. The trailer tow package includes rear anti-sway. Best wishes, not all trucks are the same wrt to towing.
