Not familiar with that hitch but you’ve already made your first “newbie” mistake, buying a trailer that is too much for your 1/2 ton truck. It may fall within your fictional tow rating and the dealer probably said “no problem” but at at nearly 36’ and likely 9k+ loaded you’re going to exceed several of your truck’s ratings and not have an enjoyable tow experience.
My tt is a similar layout but starts out 1k lighter than yours. We started with a 1/2 ton as well but after a summer you can see in my sig what we use now.
