If your rails are ISR (Industry Standard Rails) then yes, you can easily swap out your 16k sliding 5th wheel hitch for a Curt A20 5th Wheel Trailer Hitch w/ R20 Slider - Dual Jaw - 20,000lbs # C16541. An easy way to see if the rails are ISR is to measure the distance from center to center of the rails. If you get a 22" measurement like in the picture below then you have ISR rails.
