Reese Goose Box 5th Wheel to Gooseneck Adapter and Determining Pin Weight  


Hi, I have a 2017 Grand Design Reflection 337 rls, with a gross weight of 13995 and pull it with a 2017 RAM 3500 dually. Although the trailer weight is under 16K, I worry about pin weight. Can you tell me the correct Goosebox for my application? I have added a Splendide Washer dryer combo up from in the closet adding to the pin weight. Also can you tell me the weight of both the 16K and 20K? Thank you

I recommend the Reese Goose Box 5th-Wheel-to-Gooseneck item # RP85FR. The Goose Box has an fully enclosed air bag and dual shock absorbers for a smoother ride. It has a trailer weight capacity of 20k lbs and a tongue weight max of 4k lbs. This Goose Box weighs 195 lbs. The 16k lbs Reese Goose Box item # RP94716-61301 weighs 178 lbs.

This Goose Box is designed to replace Lippert 1621, 1621HD, and 0719 pin boxes. Lippert pin box 1716 will work with this Goose Box, but a spacer kit item # RP61301 is required.

The tongue weight or pin weight is typically around 20% of your loaded trailers weight so 16k lbs trailer weight would be 3200 lbs. Your trailer loaded up to 20k lbs would have a tongue weight of 4k lbs.
