Any reason I should not rewire?
When I turn my battery cutoff switch to "Off", there remains a parasitic draw on the batteries from various detectors, etc. I wish to remove this draw so that I can keep the 2 12 volt batteries fully...

My guess, as others suggested, is that it's your brakes for the breakaway switch. Don't alter it if it is that.
Where does that bus bar next to the disconnect switch get wired into things—is it on the battery side of the switch, or on the switched side? If it's on the battery side, probably one or more of the wires leading off of the circuit breakers there goes to the detectors etc. that are causing the draw, and this particular circuit could somehow be switched over to the other side of the disconnect switch with more or less impunity. There are many other things that might be wired on the unswitched side of the shut-off switch for various reasons—slide out or entry step motors/controls, levelers, an inverter (mostly because of the large current draw which may overtax the contacts in the switch), the converter (so you can charge the battery with the shutoff switch off), the charge line from the truck connector....
