Blue sea makes some great products, if your start battery is dead mid ocean it's not like you can call AAA for a jump. If anybody knows bulletproof systems this company can help you out. I bought a cole-hersche smart isolater that prioritizes the engine start battery charge via peak voltage state first whether power from my alternator or my 3 stage smart converter,/charger on shore power then switches to charge house batteries to voltage peak. So far so good, but I have not boondocked for an extended period as the isolater holding coil burns an amp or two power to operate. May well have an Achilles heel that will bite me in the butt. Much smarter/experienced campers out there than me.

Tom,

That would work if installed in the line to the "salesman switch" (manual or solenoid) but would definitely not work for any inverter installations.

Said another way, 65 amps capacity should be enough for "normal" 12 VDC draws (verify draw if you have the 12 VDC air compressor for air leveling).

But, with an inverter/charger, both on charging and inverting, you could draw/pass through well more than that.

Yes Sir, those were my exact thoughts as well!  The "Salesman Switch" basically does the Function of Eliminating the DC Draw, manually, but in the event let's say if it was forgotten about the draw would be stopped Automatically!  Guess that would be the best placement anyway, but would like it Incorporated in the Entire Loop, of course!  The Inverter does take care of the AC Shutoff, but not DC of course!
