Hey John, welcome back and thanks for the pictures! What you have now is a Lippert 1116. Assuming you just want a standard pin box upgrade, the MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert 1116 # MR87VR you were looking at is a great option.

If you were thinking about a gooseneck pin box upgrade I recommend the B&W 5th Wheel to Gooseneck Pin Box # BW73RV. You will also need the Shim Kit # BW57MV to match up to your 1116 bolt pattern.

Where are you headed once you get your new pin box installed?

Do any of the Gen-Y or Curt products fit? I do not want a gooseneck.

@JohnM the Gen-Y # GY45SR will work and is properly rated for your GVWR. The Curt Air Ride # LC155943 will also fit.

Since my GVWR is 15,600, would the 14K to 18K version be better, assuming the bushings are designed for certain weights?

@JohnM yes, sorry, you want the # MR87VR. It has an actual capacity of 19,000 lbs which is what I had on my mind right after talking to Lippert. The trailer came with a 19k Lippert 1116. I went ahead and changed it above as well.
