I have purchased a 2018 Keystone Avalanche 385bg fifth wheel. How do I know if it will work with the kingpin on the trailer??

Expert Reply:

The size of the king pin on the trailer's pin box is an industry standard. Therefore, the B&W Companion 5th Wheel Trailer Hitch part # BWRVK3400-5W will work with your trailer unless you have a Sidewinder/Revolution pin box. In order for this hitch to work with your 2012 GMC Sierra you will also need the B&W Turnoverball Underbed Gooseneck Trailer Hitch part # BWGNRK1012.

The B&W gooseneck and 5th wheel hitch is one of the best options on the market. It will allow for you to tow both 5th wheel and gooseneck trailers. All B&W products are made in the U.S.A. and come with a lifetime warranty. In order to complete you towing setup I also recommend using an in-bed wiring harness like part # 41157.
