Congrats. I never had any issues with my old half ton and it pulled my trailer just fine….but I was overweight and decided to error on the side of caution and get a bigger truck. I also knew at some point we would look to get a bigger trailer so I went with a single rear wheel one ton. The biggest difference for me is how fresh I am after a long drive pulling the trailer; I never noticed I was stressed or wound up with my half ton until I pulled my trailer with the new truck a few times.
Enjoy your new truck and safe travels.
