Adding Air to Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter


I recently bought the 16k Reese Goose Box and can not add air to the air bag. The dealer installed everything and when I got home I tried to add air with my 150 lb air compressor, and air will not go in. Am I missing something or is there a trick to it?

Adding air to the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94716 is a fairly straight-forward procedure but there are some steps you need to take to add the air. Attached is a clip from the linked instructions but I am adding the text here as well:

1. Perform the hitching procedure before adjusting suspension air pressure, with the trailer loaded.

2. With trailer hitched to truck and landing gear / jacks retracted, add air to the air bag fill valve shown in figures 12 and 13. When filling the system, you must push the air valve into the hard stop to allow the system to take air (approximately 0.25”)

3. Fill until the Goosebox is at its nominal position (seen in the air inflation indicator) (figure 14)

4. It may be helpful to put tow vehicle in neutral to allow the unit to find its natural position. Then apply brake.

5. Recheck Air Inflation Indicator / inflate to desired ride comfort position.

6. The Goosebox is equipped with an automatic air relief valve. If you try to over inflate the bag, the relief valve will pop, releasing air.

If you are following all of these steps and still having trouble please let me know and I can help you troubleshoot further.
