I've got a 2021 Ram 1500 Bighorn 4X4 Crew Cab, Short Bed, 5.7L eTorgue 3.92 Rear Axle Sport Edition with the 20" Bridgestone Dueler Tires (44psi max). I pull a 33 foot TT w/ 7500GVW in the mountains of WNC about 4-5 times a year. My truck is loaded up with about 700# in the bed, 2 adults, and a fiberglass camper cover when camping. I used my equalizerhitch brand hitch with square sway bars, originally set up for my 2001 Chevy 2500HD 8.1L Gas , 3.72 Rear Axle, 4X4, Extended Cab truck , Short Bed, 80,000 miles (dry weight w/ camper cover is about 6500#). I had to install Air Lift 1000 airbags inside the rear coil springs of my Ram 1500 and completely redo the equalizerhitch setup. I put about 45psi in my Air Lifts, 46psi cold in my tires (we don't experience really hot temps). Rear end of Ram is less than 1" lower than when unloaded and unhitched. Now the Ram doesn't ride as firm as my old Chevy, just a tad of sway, but I feel the power is close, if not equal, to the 2001 Chevy 8.1L. , using the tow mode, which I also used in the Chevy. I hold my speed to 65mph or less. I only have about 2,700 miles on my Ram, had it 9 months, so I won't be changing tires out anytime soon. I'll probably will go with a heavier load tire when I do, but the Bridgestone's are a nice riding tire.
