I found some info online. Everything is done at the Warren Plant except the rim installation. The Black Rims are strapped down in the bed of the truck and are part of the Dealer Prep. The Dealer is supposed to put the Black Rims on and you should never see the original factory rims on the truck you are buying let alone getting the extra set with the truck.. As stated above..... I will never take this truck back to that dealer.. Obviously they do not know what they are doing.
