Question:

I own a Curt Q20 5th wheel hitch and it’s attached to a what I believe is a Curt R20 mounting plate. The truck I sold had 2 flat rails that sat in the truck bed that this was attached to for use. My new truck is a 2017 F350 Dually with the Ford factory puck mounting system. How do I my Q20 5th wheel into this setup?

Hey Tim! Is your new truck a long bed or a short bed? If you have a short bed and need to keep the slider then the Adapter Rails for Curt 5th Wheel Hitch # C88KR you looked at will work. This will mount in the puck system on your F-350 and turn it into industry standard rails just like what you had in your old truck.

If you have a long bed now and no longer need the slider then you can swap out the base on the Q20 with the Curt OEM 5th-Wheel Hitch Legs for Ford Super Duty Towing Prep Package # C16017. This will let you mount it directly to the puck system without the need for an adapter.

What kind of 5th wheel do you have?

Hey Tim, did you decide if you need the adapter rails or the hitch legs for your new F350? I'm curious to know how it worked out for you, as it could help others with a similar setup.
