Personally, I prefer to use the 7 pin connector I installed in the back corner of the truck bed. It keeps the cord from dragging on the road and getting tangled/hung up in whatever. Everyone knows, give a cord, cable, or hose a chance to hang up on something, it will show you how well it can do it.
