I put michelin LT M/s2 E rated tires on my F150 That got rid of the squishy p rated wranglers. You say you upgraded with the Cooper c range tires what was the upgrade you need to be on D or E rated tires to make a difference. I also put a set of Timbrens on the truck. Those 2 changes have made a world of difference. I also have the Blue OX sway pro and my Tongue weight is 1040 loaded and ready to go. I realize that I tow at near my max weights but not over and I give myself extra caution. I never exceed 65 and mostly stay 60-62. If you can stay within your truck Manf limits. And discipline yourself to stay within your guidelines you can tow with your truck all day long. If not get into a bigger truck.
