Expert Reply:
The Demco rail adapter kit that you need for your 2020 GMC Sierra 3500 HD is part # DM6333 which is different than the part # DM6194 which was referenced for the 2019 model year. The adapter # DM6333 has a 21K weight capacity and it is compatible with your puck system whether you have the long or short bed.

I bought a curt fifth wheel plate for my 2019 Chevrolet with the factor pucks in the bed. worked great but since then I purchased a 2020 GMC 3500 and the puck position is closer together and cant be used so no camping yet this year. Can I get new bolt on sides to fit my 2020.
