Hey Scott! The 4-1/2" spacing you’re seeing on the #DM79FR is the standard bolt pattern used on most flat mount couplers. Unfortunately, we do not carry a coupler that matches your 5" horizontal spacing with the mounting holes 2" apart…

Hey Michael, yes the Demco cigarette lighter outlet kit part #DM83FR would work to give you a power outlet that your Stay N Play part #DM86VR monitor to be powered from. Another option would be a USB to cigarette lighter adapter which isn't…
