Fifth Wheel Rail Slot Dimensions that Reese Fifth Wheel Hitches Use for Installation


I have a Dodge 3500 its a 2004. With 8foot bed. Just bought the truck with fifth wheel rails on it. They only have the inside four slots. Its rhino lined to the truck bed so not sure what company made them. Im towing a 38foot 10500 lb. fifth wheel trailer. Would like to make sure fits before purchase.

The Reese fifth wheel hitch part # RP30047 is designed to install in the middle slots of a rail that are 20-1/2 inches apart on center left to right and 22 inches apart from one rail to the other.

I attached a picture that shows the dimensions of the industry standard fifth wheel rails.
