Today on our 2000 Dodge Full Size Van, we'll be installing the Curt Hitch, part number 13015. This is what our hitch looks like installed on the vehicle. Now we'll give you a couple of measurements in helping you choose some accessories for your hitch such as a ball mount, bicycle rack, or cargo carrier. From the center of hitch-pin hole to the outer most edge of the bumper is approximately 3-1/2". From the top of the opening in the receiver to the ground is approximately 17-3/4". Now let's install our hitch. First we'll point out the locations where the hitch will be mounted to the vehicle. There are three on each side. Next we'll point out the hardware that will be used to mount the hitch to the vehicle. We will use the 1/2" carriage bolt as well as a spacer block and a hex-flange nut. The hardware will be installed as follows.
