The 15-inch and 17-inch adapters for 13 to 14 and 15 to 16-inches measurements respectively. You have to get the accurate measurement and adapters.

One more thing you need to keep in mind about the dimensions for a tight fit. You should not go for the adapter in which height is fixed if you are confused about the dimension. In this case, you need to go for the height-adjustable models which are pricey. So, the budget also matters here. You may need to make a negotiation.

Do I need to replace The fifth wheel hitch or the Pin Box?

Now the question is that do I need to replace the fifth wheel hitch or the pin box? The answer is up to you.

Then, the next one which replaces the fifth wheel hitch. Although this model occupies a lot of space, this one is more secured and safe. This type of setup needs a truck bed equal to or more than six feet.

The third and last one, this type of setup used to replace the existing trailer pin box. This type offers you an easier installation method although it requires more maintenance.

Do I need to look for any additional features?

Although all the 5th wheel to gooseneck adapter will satisfy you with your towing job, still there are some extra features that will make your adapter more efficient and effective. The features may be safety, security and cushioning as the main areas.

The maximum tongue weight should never be higher from towing capacity. It should be 10-25% lower than the towing capacity. It is better loading your trailer on the time when 60-percent of the weight is placed before the axle. A  trailer with a well-distributed weight and perfect tongue weight will make the rig form a straightaway line keeping your trailer entirely horizontal.
