Question:
I have a 2016 GMC Sierra Z71 2500 HD with the short bed and recently purchased a camper that came with the Demco 6077 Auto slide hijacker hitch. I currently dont have a prep package in my truck and would like to install and under bed package that will fit this fifth wheel hitch. Can you please supply me with the correct part numbers that will fit the hitch and my truck

Hello John, thanks for reaching out. We have just the thing! I recommend the following:
- Demco Premier Series Custom Mounting Brackets for 5th Wheel Above-Bed Base Rails # DM8552011
- Universal Above-Bed Base Rails for Demco Premier Series 5th Wheel Trailer Hitches # DM6071
This will be everything you need to add a set of industry standard 5th wheel rails to your bed. The Demco Hijacker is made to work with industry standard 5th wheel rails.
What kind of camper did you get? Just curious.

Hey John, did the Demco mounting brackets and base rails work out for your truck and hitch setup? I'm asking because it could help others who are looking to install a similar setup.
