I installed a disconnect in the lid of the battery box which resides on the tongue right behind the battery. I installed the switch on thw ground cable. No issue with forgetting even with my feebel mind. When getting prepared for departure the last thing I do is disconnect shore power, store the cord, then raise thew tongue jack to hitch height. If the jack don't work then disconnect is on.

That's the way mine was; if the disconnect was thrown jack no workee....no hitch the trailer.

Nope, you simply break the positive after the breakaway connection leaving the breakaway switch as the only thing with power. The breakaway won't be a drain on the batteries unless you pull the pin.
If you break the negative, everything including the breakaway will be powerless.

If you really worry about the breakaway, take the positive wire and attach directly to the battery positive post, the breakaway switch is normally open and will NOT create parasitic draw on the battery.

Correct, but if you break the negative, there is no way possible to power the breakaway.

I installed a switch like post #2 on the side of my battery box. Switched the positive terminal.

Buy Quality Switch
Whatever you do, don’t buy the cheapest switch on eBay for your disconnect. Spend the extra dollars to buy a quality switch or you will get stuck in the future when the cheap internal connections decay. Remember—all circuits on battery use this switch and it needs to be able to hold up.

I'm talking using the disconnect while rv is being stored & breakaway not needed.
Also if I decide to move the rv with the cable removed the jacks won't work, nor the breakaway, til the cable is reconnected.
I talked to fellow rver that said while his rv was in storage with the disconnect off, the breakaway still had power, that some ahole came through the storage pulling the breakaway pins on the majority of the RVs thereby burning up the switches, brake wiring & ruining batteries. With the negative cable removed that can't happen.

I'd like to add a battery disconnect, since our Passport didn't qualify for such an extravagance.
I've looked at some different types, and some require a hole cut into the chassis to mount the switch, and I won't do that.
What are my options?

If you have the dual posts, screw down type, this works great.

The one from post #2, that Chuck provided a link to is the same I have, easily remotely mounted, and also easy to see if on or off. My battery box is sealed with about six or so screws.

On anything I put a switch on I always put it on the Negative cable ...
it will not corrode as a Positive cable will

Ok. I bought and installed this last year: https://www.bluesea.com/products/600...__Knob_-_Black
The manufacturer's wiring diagram showed connecting to the positive terminal. So I did (it cuts ALL power from the camper except the jack.) So by using the positive terminal, instead of the negative, what kind of a mess have I gotten myself into and is it merely a preference by most or a requirement?

wont hurt anything .....
I was just explaining my preference because I i have seen corrosion on switches in truck applications ..where the intent is to totally disconnect power

Personally Battery disconnect switches are just another source of potential problems to induce into the 12 volts system... Id have just remove the negative terminal from battery and brought the battery home and out ion a maintainer...
Yea its a slight pain but the battery will always have a full charge this way.. I cant tell you how many folks I have helped troubleshoot NO 12 volts from battery issue down to a battery disconnect switch...
But.. you've got it installed and Id have installed it on the negative side.. Some passing thru yanks your battery break away cable and you will come back to more than a dead battery

Its not pretty but its installed with new cables. Had to replace cable going to negative terminal as well because it was too short to reach the disconnect switch. You can't see it, but there is silicone where I drilled the 1" hole for the switch. Had to grind some of the round plastic part of the switch to make it fit with the angles of the box lid.
I sprayed it with black when finished and put the extra cable inside the battery box (forgot to take a pic).
Then I went home and put a bunch of stuff on CL (old WDH, 30 and 50 amp surge protectors, 4 bike bumper rack, curt hitch for the wifes Journey). Within 5 mins, received 4 scam texts. Now I remember why I put off posting on CL. "Can I send you a code to verify that you are a real person?" I received that 3 times from different people with LA area codes...im in GA!

Craigslist is horrible. Once the scammers have their fun the bogus responses tapper off to nearly non-existent. I have a new, in the box, camper cover that was given to us by a neighbor who sold his camper. This cover is too big for ours and I told him I’d sell it and do the work selling it and then split the proceeds with him. It’s been over a year now, one bite of a low ball offer. We’ll hold out for a decent offer.

I personally like this in place of the "fuseblock" on the frame. Breakaway, hitch are attached directly to the batteries and are not shut off with this.
