Can You Put A Reese 20K Goose Box On A 2021 Open Range 374BHS?


Can I change out the factory installed Lippert pin box on my 2021 Open Range 374BHS with the Reese 20K Goose box RP94720?


Expert Reply:

Yes you can remove and replace the factory Lippert pin box on your 2021 Highland Ridge Open Range 5th Wheel.

First lets find out what 5th wheel pin box you have. Pin boxes are a custom-fit item; however, there's no way to determine which one you need based on the year, make, and model of your trailer.

The easiest way to replace your pin box is to find the pin box's manufacturer tag along with its specific pin box number. These are both typically located on a sticker on the pin box or on the king pin itself. This pin box number will usually be 3-4 numbers long and can have letters attached to it. Some very common pin box numbers are Lippert's 1621, 1716, and 1116 pin boxes.

I have attached some articles to help you in detail to find out this information.

Once you have the Lippert model number you can go find the specific model of goose box you want.
If you do like the idea of having an air ride gooseneck instead of a torsion gooseneck, the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter - Lippert 1621 and 0719 - 20,000 lbs # RP94720 is the way to go. The air bag can be adjusted to provide a smooth ride for both your truck and trailer/camper.

A good alternate goose box is the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621HD - 25K GTW - 4.5K TW # GY38FR. The Gen-Y is sturdy but lighter and has little to maintain, and no internal parts or air bags that can fail and need to be replaced. You just have to grease two points on the hitch. It has an auto latch and pull cord that lets you stay out of the bed of your truck when coupling or decoupling your trailer. It comes with a scale on the hitch so you can easily see and adjust your tongue weight.
