YOU ARE THE ISOLATOR. Many do nothing and leave switches same way forever. All batteries feed load and charge tantamount to just one battery. That's why an isolator works. KISS works if you do your part switching.
If you pay attention and give TLC ( charging) when needed- all is cool.
Without an isolator you have to remember ALL when running and charging. Then switch it to disconnect your START battery from you HOUSE supply battery. Forget to switch off, and you drain all batteries down including your START battery when adrift. OR.... Forget to switch in the batteries in parallel while running, your HOUSE battery never charges.
I've never had an isolator and did switch that GUEST knob around 100's of times.
