Do you disconnect the electrical plug from your car/truck when stopping for an hour or so to shop?

I use to disconnect the 7 pin on my old tow vehicles but my current Ford tow vehicle's factory tow packaged disconnects internally when I shut off the ignition. I don't disconnect now unless it's time to unhook at the campsite. I get 5.5 amps when idling and more when driving so plenty to power my 12 volt fridge and keep the batteries topped off when towing.

We installed an isolation relay when we bought our Tab. It works well. Not too difficult to install if you have electrical savvy.

As noted by others, neither unplugging the 7pin, nor an isolation relay, will save your Tab battery, if you leave your 3-way fridge going on 12V for any period of time (been there, done that!)...

We used this one (West Marine carries it):

Where exactly does this get installed?

The reason I ask, I had an off grid kit in built into my Jeep and would prefer not to do anything that can interfere with it.
