You shouldn't use a hitch pin or the ball on your hitch. Get a 2" shackle from agency6 and do it correctly. Has to do with the forces you are applying to the pin and where the strength is.
Im happy because i really like the truck. I cant complain because I wanted one and got it. I think in my lifetime Ive never paid more than a few thousand below msrp, as we all have. In 2021 almost 2022 for a 4runner in San Diego that will not be the case.
