Hello All. I will be towing with a 2020 GMC Sierra 2500 Gas truck. What do I need to purchase for a ball when I drive down to Tennesee? Also, is the Anderson hitch worth ordering for this TV? I have seen various posts for balls and ones that can be lowered, so I am not sure which to order. Seems to me as if the truck and Oliver Elite Ii are both about 23 inches at the towing connection?
