Hey Rick! The B&W Companion Fifth Wheel Hitch item # BWRVK3500 base measures 30-1/2" wide x 36" long. This is the complete 5th wheel hitch and head that goes with the Replacement Base item # BWRVB3500 you mentioned.
The base will measure 18" from the center of the square post, where it connects to the gooseneck, to the edge of the hitch on the cab side.
