We tow a similar sized trailer with a 2017 Chev 1500. The first thing I did to the truck was put on Bilstien shocks since the OEM ones seemed to allow too much bounce. I run the P tires at 44 rear and 40 front. The Equalizer hitch is set up to get the front end back down.
Good luck
I'm glad I wasn't as easily influenced and gullible as the OP, because unlike your response, most of the guys prodded him straight to the HD truck.
The OP can more than likely resolve most of his issues with LT tires and better shocks, or just buy a whole new vehicle.
