Hi David; thank you for providing that information and the pictures. It looks like your Blackthorn 3101RL-OK has a GVWR of 14,040 lbs. That means the best choice for a MORryde Cushioned Pin Box is the # MR83QR. This is designed to fit a Lippert Rhino bolt pattern like you have and 5th-wheel trailers with a 14,001-lb - 18,000-lb GVWR. It also has the same 21,000 lb pin box weight capacity you have now.
