The Reese Goose Box # RP85FR is specifically designed to fit the Lippert 1621 and 0719 pin boxes, so you will need to confirm your pin box number before moving forward. This can be easily done by contacting the manufacturer of your trailer to ask which was used. All you will need is the VIN and they should be able to tell you as they keep this on file.

In the off chance they cannot tell you, there are other ways to verify which one you have. First will be to check your pin box for a label. The manufacturer and model number of the pin box is usually printed on a sticker or stamped into a plate or directly into the metal of the pin box.

If the label has been removed and no stamping can be found, you can also measure to confirm you pin box number. I have an article attached that will show exactly where to measure and what that measurement will determine.
