I have checked with my contacts at our gooseneck adapter manufacturers, and adapters are compatible with the traditional trail-air pin boxes.

My contact further explained that this adapter is not compatible with Trail-Air's Rota-Flex pin box. This is due to the forward and rearward movement in this pin box.

If you have a traditional trail-air pin box that then this adapter will work great for you.

A very popular option is the Convert A Ball part # CAB-C5G which will attach to the king pin and provide a gooseneck coupler.

The adapter can indeed be used with an offset hitch ball, but since you're going with this style of gooseneck adapter anyway, you may as well use the offset version # CAB-C5GX1216 instead. The adapter itself provides a 7-1/2" offset for cab clearance with your short bed truck.
