I pulled our 6000# 28' travel trailer all over the place with our '19 laramie 1500 4x4 ccsb. tongue wt. will vary a lot by trailer but ours was under 600# when loaded for travel and I never had any trouble with sway and the trailer tracked great. these trucks have great brakes and I set the brake controller at 5.5 and never had any trouble stopping. I changed out the sway bar to the Helwig and put airbags. I ran around 25# when towing and added a few pounds to the tires to stiffen up things when towing. cruised at 68-69 and got 8.5-10 depending on terrain. get yourself a good WDH and use tow/haul. you will be at the upper end of what that truck will comfortably tow. maybe plan for 65 mph and dont pack much in the truck bed. get it weighed to see exactly where you stand.
