Towing a Gooseneck Trailer with a 5th Wheel Trailer Hitch on a 2002 Ford F450 Flatbed


I just bought a 2002 f-450 with a Reese 5th wheel hitch on it , and want to use the present configuration to pull a goose neck, its a flatbed the hitch has large pins in it to remove the saddle from the mount. The part #s 58079 and 49080 look nothing like my mount, mine is very heavy duty and sits on the flat bed. Guessing probably 10 yrs. old. Have pics. but unsure how to get in this message.

The 2 gooseneck hitches that you have referenced are designed to fit in above the bed 5th wheel rails that the Reese low profile hitch # RP30054 does not fit into. The low profile hitch requires a custom installation and there should be a 1/2 inch thick steel plate under the bed and attached to the truck frame and this is what the hitch is attached to.

In order to use the hitch with a gooseneck trailer I recommend replacing the inner tube of the gooseneck coupler, if it can be removed, or replacing the entire coupler with a new one. You would be using an inner tube that has a king pin on the end of it, like # 2085205 which has a 4 in outer diameter and is held in the outer tube with set screws.

We also have inner tube # BD0289650300 which is 4 inches square and is held into place with bolts instead of set screws. We also have the inner and outer tube together to replace the entire coupler, # BD0289590300.

Then there is a round 4 inch diameter inner tube, # BD0289640300, that is held in place with bolts and not set screws. One of these is going to be the best option for your current set up. I also linked an FAQ that should help.
