Question:
2020 F-250 6ft bed. I have Curt rails stamped CMI that’s says will fit all “industry standard hitches”. What are the mounting specs for this hitch? And will they fit my Curt “universal” rails?

Hey Gage. Since the rails in your 2020 F-250 are made by Curt and say industry standard on them they are definitely compatible with the Demco Autoslide 5th Wheel Trailer Hitch w/ Slider item # DM8550034. This hitch only fits industry standard rails and will connect right to it with the included set of pins. As far as I know Curt never made rails that weren't industry standard and definitely not for as new of a truck as you have.
To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C57008. This harness puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel trailer easier and more convenient.
What kind of 5th wheel trailer do you have?
