How to select a suitable 5th wheel to gooseneck adapter

The clearance

To decide whether you can use a straight adapter or not, the first thing to do is obtaining the trailer width measurement. Next, divide that number by two and write down the result. Now you need to measure the distance between the back of the truck cab to the adapter planned position. If that distance happens to be at least 4 inches longer than the first result, you can use a straight adapter here. The clearance is good enough to allow an unobstructed installation of the adapter. Trailer couplers would also have a stable and reliable connection.

For a quick example, let’s assume that your trailer width is around 96 inches. One-half of it would be 48 inches. Add in 4 inches and now you have 52 inches. If the measurement from the gooseneck receiver to the truck cab is 52 inches or more, a straight adapter can be installed. If you don’t have enough clearance here, an offset adapter would have to do. The offset of the adapter can lengthen the clearance by 7.5 – 8 inches, depending on the type and brand.

The height

In order to decide the appropriate height for the adapter, get the car and the trailer to park on even ground. If you are having a problem then a jack would be useful here. When the trailer appears to be steady and level, back the truck toward it as if you are about to connect them together. After that, get to the truck box and measure the gap between the top of the gooseneck ball to the pin box (It’s not the kingpin). The measurement you get from this is the height of the adapter you should have.

To achieve a safe operation, also ensure a minimum distance of 6 inches between the trailer overhang and your truck side rails. These measurements should give you the general idea of the adapter height. The tallest height you can get with the adapter is the cushioned version at 16 inches. Some of the adapters also offer adjustable height to be more versatile to your needs.
