Question:

I just purchased a 2020 GMC Sierra 2500HD crew cab, standard box with the OEM puck and gooseneck system. Im trying to figure out what my best hitch options are? Im towing a Grand Design 310gk. With this set up do I need a slider hitch?

With the longer 6-3/4' bed on the newer GM models like your 2020 GMC Sierra 2500, you could potentially use a fixed hitch like the B&W Companion OEM 5th Wheel Hitch # BWRVK3710. But you would want to do some measurements to be sure this will work. I have included some steps below that you can use to determine if your truck and trailer combination will work with a fixed hitch.

Steps Needed to Determine the Turning Clearance You Have When Towing a 5th Wheel Trailer with a Tapered Nose:

1: Go to the far edge of your trailer nose, about 1 foot up to allow for the curvature of the nose you will place a piece of tape with a string hanging with some sort of weight (a lock would work). This will create a point you can use for measuring.

2: You then want to take your measuring tape and measure from the center of your king pin to the string.

3: Take the measuring tape to the bed of your truck with your 5th wheel hitch properly positioned in the bed.

4: You will want to position the end of the measuring tape in the center of where your king pin will sit in the jaws of your 5th wheel hitch.

5: You will then extend the tape towards the truck cab to the measurement you got from the center of your king pin to the string.

6: You will want to keep the the end of the measuring tape centered in the king pin jaws and use that as a pivot point.

7: You will then rotate the other end of the tape using that pivot point, if you can rotate the tape all the way through without making contact with your truck cab then you have enough turning clearance to use a fixed hitch.

If you make contact at any point, then you would need a sliding hitch like the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3775.

Both the fixed and slider B&W Companion Hitches are sourced and made in the USA and will attach directly to your prep package without the use of an adapter.
