Expert Reply:
There are actually 2 Reese Goose Box options. Each one fits different pin boxes.
Goose Box # RP85FR fits Lippert 0719, 1621 and 1621HD pin boxes and Fabex PB-600 Series pin boxes rated up to 20,000 pounds.
Goose Box # RP94716-61301 fits Lippert 0115, 1116 and 1716 pin boxes rated up to 16,000 pounds.
The pin box manufacturer and model number should be on a sticker or plate on the pin box itself. If that information is not available you can take some measurements of the pin box using the link I have included to determine which model you have. If it is not one of the models listed above then none of the Goose Boxes will fit.
