2016 Open Range Light 319RLS

Thanks for the information, Chris we pull our Cougar 320 SRX with a aftermarket gooseneck adapter since we have several other farm trailers with gooseneck couplers.It works great and the Cougar is a little heavier than the Open Range. I researched the Open Range King Pin Combo on the web and did not have any luck finding out how the factory set up was installed, is yours set up basically like a aftermarket hitch from the factory ?
Thanks Bruce
