The Demco Hijacker Auto Slide 5th wheel hitch is a great choice for short bed trucks.

For the 2021 GMC Sierra 2500, you'll want to use the # DM8550035 which is compatible with the # DM6333 adapter that fits into the GM puck system (assuming your truck is equipped with the puck system).

If your truck doesn't have the GM puck system, and you want an under-bed mount you'd use the # DM8550037 along with the Demco # DR37FR under-bed rails.

If you'd like to install a 7-way connector in the truck bed so you don't have to run the trailer connector wire up over the tailgate, you can install one using part # HM54FR.

I've linked to a product install video for the trailer wiring harness I mentioned above.

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
