Auxiliary power supply for rv

[BillnDeb]

Our rv didn't come with a battery turn off switch and looking to find an auxiliary backup power supply or an OEM cutoff switch to install.

Always best to post the year, model and make of your RV and tow vehicle for best advice.


I went on Amazon but a lot of places sell cut off switches the run from simple to expensive. I went for a rotary switch which failed after a few uses and now have on like this one for $6.99. I simply unscrew it part way and no connection. Or take the knob off and leave it on the battery.

We have a 2019 Jayflight 29BHDB and have a 2018 RAM 2500. Thanks and we'll look into that.

My battery has a screw terminal so I used a slightly different version of the switch above. Works like a champ. Got from Amazon.

It says it is for a side post battery but my screw terminal was on the top.

Thanks

Our battery is the blue Optima.
