Can Goose Box be Used with Short Bed Truck


Ive been researching the Goosebox 20k to swap out my 5th wheel. I have a 2015 GMC Sierra 2500 standard bed not long bed. First, will this work with that? If not, what are my options? Thanks

The Reese Goose Boxes like the 20K Air Ride # RP85FR referenced in your question are pin box specific. This means they are designed to replace specific pin box models on the trailer so you will want to first make sure that it will be compatible. This particular unit is designed to replace the Lippert 1621, 1621HD, and 0719 pin boxes. The existing pin box on your trailer should have a sticker or plate on it that lists its model.

Turning clearance may indeed be an issue with the Goose Box installed as it does not provide any type of offset and you won't be able to rely on sliding travel from a sliding 5th wheel hitch. If you have been towing a 5th wheel trailer with your existing truck and a sliding hitch was needed to execute sharp turns then the Reese Goose Box won't be a good option.

For a short bed truck like your GMC Sierra 2500 a better option is an offset adapter that bolts to the existing king pin (instead of replacing it) like the Convert-A-Ball # CAB-C5GX1216. This will bolt to the king pin so you can tow your 5th wheel trailer with a gooseneck hitch in your truck. It features interior polyurethane cushions that act as shock absorbers for a smoother ride and it has a 20,000 pound towing capacity. Its 7-1/2 inch offset will provide additional cab clearance for making sharper turns.

Please note though that an adapter like this is not recommended for use with factory-installed rail/puck systems.
