12v shut-off

If my 5th wheel is parked for a couple of months and my solar panel is keeping my battery charged, should I turn off the battery disconnect switch or just leave it on?
  • My first trailer did not have one. My current one does. It's hit or miss if the manufacturer installed one or not. Probably more do NOT install them if I were to make a guess. You are then forced to just remove lead from the battery, or install your own.
  • My buddy recently bought a used Sabre and we can’t find a 12v kill switch. Do some trailers not have them? The leads coming off the battery seem to terminate on a breaker before splitting and running in different directions.


    No they are not a standard option they put on. My last 2 did not have them and I bought my own and installed it.
  • Thanks guys, I'd love to know the reasoning behind that. I thought all RV's had CO sensors that draw power 24/7 and not conducive to long term storage without a switch.

    Your correct and that's why so many new owners complain of dead batteries in their new trailer. All that grief for a $14. discount switch.

    What I can't understand is the dealer not explaining this to a new owner.

    Yep, my 2013 Sabre (bought in 2012) did not come with a battery disconnect from the factory.
