Thanks for the education
I am officially an "Old Fart", even though my DGD hates when I say that and I have been around a lot of stuff in my 73 years here on earth. I have learned an awful lot both formally (16 years of scho...

I've made my own battery isolation properly fused switching devices for nearly 40 years now using a simple cheap Trombetta HD isolation solenoid, an 80 amp marine slow blow large fuse in it's screwed on holder, and 2 small pieces of 1/8 X 1-1/4 angle iron screwed together for mounting the components on and the assembly under the hood. Takes less than a hour to make with most household tools. Bomb can prime and paint the angle iron the color you desire after drilling all holes.
Carry a spare fuse in your glove compartment if it should be ever needed and if the solenoid should ever go bad, you can get another at about any auto supply store or so many other places in nearly any city or population center. Sometimes called an HD starter solenoid. OR, just carry a new one with you if you're paranoid. They are cheap and small and takes only a couple minutes to replace but not likely you ever wiil. I have never had one go bad yet!
A fraction of the cost of purchasing a manufactured battery isolator and totally fool proof to even RV beginners. Most solenoid's terminals are marked as to 12 V in and out and positive (+) current wire actuator connection from the ignition on wire which is what powers the solenoid's magnetic coil to connect the 2 battery systems together. Also if a toggle switch method is wanted to couple the batteries together. Turning the vehicle ignition key to off and the 2 battery systems (RV and vehicle) are disconnected immediately. Most solenoids have the steel housing ground (negative) and/or offer a negative (-) current stud also if the solenoid is bolted to a non-electric surface like plastic or if the vehicle etc system has an isolated ground (very rare). Must have both + and - feed to the solenoid for it to activate.
I won't go into depth about other solenoid hookups such as an inverter or other items you want to turn high current off and on as desired remotely either automatically or manually by remote control activator or a handy close by toggle type switch. It's easy but you need a little understanding of electrical system hooking up so you don't burn something out or fry wires.
Edited to fix mispellings in my haste, DUH!
