Question:
I bought a BW companion slider base for a 2025 gmc. I have the Ford version of this hitch. Do the pivot arms mount in the same position on the gmc base as the Ford base? The Ford base was set up to fit my camper, should the gmc base be set to match?

Hey Richard! Welcome back. You need to use the chart from B&W for the # BWRVK3775 which I attached below. I believe you will be using the short bed king pin 2" behind axle configuration, make sure to verify that. Then choose the height that will make your trailer as level as possible. I went ahead and attached a link to the complete instructions further down on this page for your reference. Let me know if you need anything else.

Hey Richard, did the chart from B&W help you set up the pivot arms on your GMC base to match your camper? I'm asking because your experience could really help others with a similar setup.
