Gooseneck to King Pin Adapters Compatibility with Grand Design Solitude with Rota-Flex Pin Box


Can i install a gooseneck ranch hitch on my Rota-Flex pin box? all my trailers are goosenecks except my new 35foot Solitude

The Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter # AM3100 will not work with any cushioned pin pox like a Rota-Flex, however there are a couple of options for you to make the Solitude compatible with your gooseneck hitch.

One option is to use the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter - Single Jaw - 21,000 lbs # DM8550045. This allows you to keep your current pin box and will simply install over your gooseneck ball for an easy connection to your truck.

Another option is to use the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR. This pin box replacement for 1621, 1621HD, and 0719 pin boxes offers air ride and a direct connection to your gooseneck hitch. There are other pin boxes that are compatible when you use the spacer kit # RP61301. If you go this route, let me know the numbers on your current pin box and I'll be happy to help ensure you get the correct fit.
