What Reese Pinbox do You Recommend for My Keystone Montana 3791RD with Lippert 1116 Pinbox?


I have a 2022 Ram 3500 Dually pulling a Montana 3791RD currently has a Lippert 1116 Pinbox that I want to replace with the RP94716-61301 Goosebox. My Montana has a shipping weight of 14,228 lbs, carrying capacity of 2,372 lbs and hitch weight of 2,620 lbs. Is it too close for comfort to use this product? As I understand it, the Reese Goosebox is the only approved replacement goose neck from Lippert and Reese does not have a higher weight rated replacement product for the Lippert 1116 Pinbox.


Expert Reply:

If you are absolutely set on using the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler - 16K # RP94716-61301, you can still definitely use this safely on your Keystone Montana 3791RD with a Lippert 1116. However, in order to do so, you need to make sure that you carrying capacity on the trailer does not exceed 1,772 pounds in order to be under the 16k rating of the # RP94716-61301. This weight is under the maximum carrying capacity of 2,372 on your trailer. As far as the 2,620 pounds of tongue weight, the # RP94716-61301 offers you plenty of capacity.

However, if you wish to maximize the entire 2,372 pounds of carrying capacity on your Montana, Reese does offer an option that fits. That is the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter - Lippert 1621 and 0719 - 20,000 lbs # RP94720. With this option, you will utilize the full carrying capacity of your trailer. In order for this to work on your 1116 pinbox, you need the additional Spacer Kit # RP61301. This setup is the exact same as the # RP94716-61301 except with extra weight capacity.
