I have a 2021.5 vw atlas r line with 4-motion. I am in the process of buying a trailer that is 3700lb. The problem is the connection point in the tongue requires a 2 5/16" hitch ball. The vw owners manual says not to go above 2" diameter and I don't know why. The weight is ok and well under. Has anyone switched their ball hitch or not a great idea? Please help lol.
