Question:
Our company has recently purchased several of the KPG5-Q30 gooseneck couplers. We would like to purchase an adapter for an inner tube that is compatible with the same outer tube but for a 2-5/16inch ball. It will also need to be rated at 30,000 lbs. Does etrailer or the manufacturer of this product offer any options that will fit with this outer tube?

Hey Ryan, you could use the Demco eZ-Latch Gooseneck Coupler # DM43KV with the etrailer Gooseneck to 5th Wheel Trailer Coupler Adapter # KPG5-Q30 that you have. This is correct size and gives you an easier to use latch system for the hitch ball as well.
