I have 5th wheel rails in my truck from previous owner and I have been borrowing a plate that fits on the rails to tow my goose neck trailer. Couple days ago I got offered a resse 15k 5th wheel hitch that has side to side wobble also for a really good deal and bought it. More of bought it so I can tow anything. Then I was flipping thru a trailer supply magazine I seen they make a pole to remove my goose neck coupler of my trailer and install a king pin style so I could tow trailer with my new fifth wheel hitch. Is there a benefit of towing a goose neck or fifth wheel. My trailer I would change to kingpin is 36' two car car trailer.
