What are you trying to accomplish?
Only one switch is needed to kill power to the electrical system. Switch between ground and the front battery NEG terminal. Read my first post in this thread.
Chassis ground and main bus bar ground to one side of the switch and front battery NEG to the other.

Couldn't a solargizer fix your problem?

A solargizer would try to keep the batteries charged while the drain persisted.

I think in order to kill the truck with one switch you would need some sort of compound switch installed between the batteries to isolate the 12v feed from the front battery to the truck and also the rear battery from the front battery. When "on" they would all be connected and when "off" they would all be isolated. This would break the 12v feed to the truck and break the 24v circut between the batteries. (opening the 24v circut between the batteries to kill it). Im sure somone makes a switch like this but to what expense.

The OP started this thread because of a battery drain. I recently shorted my batteries bc of my handywork and going off road and hitting a rut too hard.... Anyway while my batteries were shorted out and smoking and while I was taking the bolts off with a channel locks ...I was thinking it sure would be handy to have a cut off switch on the batteries... Plus (When) I have the Starter realay problem. i COULD JUST OPEN the hood and flip the off switch.... and extra security.

Yep, thats why I put up that post about the weird compound switch. Also, Perko makes the switch, Now I'd have to verify that idea would work. Otherwise, a switch on the 24v starter feed would stop the starter in the event of a run on and would slow down an unauthorized start/theft. A ground side switch would work in a normally operating/wired truck which is not running-on already.
