To figure out the equivalent MORryde pin box replacement to the one that is on your RV, you have to identify the existing brand and its model number, which is usually located on the pin box.

I am not looking to convert to goose neck, so please don't suggest it, just looking at pinbox for the 5th wheel.In order to tow a fifth-wheel, you need to have a fifth-wheel hitch assembly. I still have the original one, which is just the basic pin box, but rather than swap them out, I was wondering what others use for a pin box that helps with the ride and everything. I have it locked in place now and the wedge removed so it acts as a standard pin box. Between that and some rust issues and others, I descided to replace the truck and now have an F-450 so the Sidewinder is no longer needed. Made for terrible handling as the pinbox would shift side to side and cause the truck to track back and forth. While it gave me exceptional backing ability beyond 90*, the wedge did not fit the 5th wheel like it should even though it is the correct one. When I bought my Arctic Wolf, I had added a Reese Sidewinder so I could tow with my short bed. I am curious what others are using for their pin box. (Hey! I noticed I can put a title in now without it jumping to here now! PATCHED! )
