Helpful Expert Reply:

The B&W Companion 5th Wheel Trailer Hitch # BWRVK3500 (RVK3500) is the complete 5th wheel hitch that will mount to an existing B&W Turnoverball Gooseneck Hitch socket in the truck bed. The part # BWRVB3500 (RVB3500) that you also referenced is simply the replacement base for this hitch without the head unit.

I have attached a couple of short video demonstrations that you can check out as well.

So RVK is the entire system and the RVB is just the base component?

@Rick Hey Rick, yep you're exactly right. Part # BWRVK3500 is the full companion hitch and part # BWRVB3500 is just the base/legs (which is included in the full hitch).
