Question:

I have a customer with a Lippert Road Armor TrailAir pin box. They are wanting to replace this to connect via a 2 5/16 ball. Would the Shocker Hitch SHK47YR be a replacement for that? 2021 Keystone Montana 3763BP Thanks for your help! Kim

Hey Kim since we know your 2021 Keystone Montana 3763BP has a Lippert 1116 pin box the correct Shocker Hitch fifth wheel to gooseneck adapter would be the part # SHK55MR. Thanks for finding that info for us (see below) so we could figure out the correct fit!

My customer can't find any information regarding the pin box. There is a tag with the number 2020044280. I also have pictures if you would want them.
