I am in the process of purchasing a 30 foot fifth wheel RV. The pick up truck that I currently have is equipped with trailer ball in the box as it used to haul a goose neck trailer. The dealer has informed me that a goose neck adapter can be hooked to the king pin therefore eliminating the installation and cost of a fifth wheel for the pick up. Is this a wise way to go ???? or would this put excessive strain on the RV? Your quick reply would be greatly appreciated.
