I would be happy to help you determine which Reese Goose Box will fit your 2019 Keystone Montana 3560RL 5th Wheel trailer, but we do not have a break down of which pin box your specific trailer has.

Instead you will need to check the pin box on your trailer for a four digit number such as 1116 or 1621. If you cannot find such a number then you will need to take a picture of the serial number sticker on the pin box and email it to me so I can identify your pin box.

When it comes to the Goose Box there is two options:

The # RP85FR which is designed to replace the Lippert 1621, 1621HD, and 0719 pin boxes and has a 20000lb capacity.

The # RP94716-61301 which is designed to replace the Lippert 0115, 1116 and 1716 pin boxes and has a 16000lb capacity.

I included video reviews of the products mentioned for you to take a look at.

Thanks for the picture! I reached out to my contact at Lippert with the numbers of of the sticker you provided and they were able to confirm that your 2019 Keystone Montana 3560RL has the Lippert 1116 pin box. Since your trailer has a GVWR of 16600lbs you will need to go with the Reese Goose Box # RP85FR with the spacer kit # RP61301. This pin box has a 20000lb trailer weight rating which is plenty for your trailer, and will be an exact replacement for your current pin box. I included videos of the products mentioned for you to take a look at.
