12 volt draw on battery

[lo442]

I have a power draw with everything off as far as I know. This is my first travel trailer it's 2017 prowler linx . It doesn't have a battery disconnect.

Suggest adding a disconnect switch

Parasitic draw from the LPG detector, if you have a clock in a 12v radio/CD/DVD player to name the two most common

Other drains include TVs, wireless control systems like the LCI OneControl, some thermostats (if they don't require a battery), etc. Anything you can turn on with some kind of remote or soft button without having to flip a physical power switch will have a draw even when off.

If you can't or don't want to add a disconnect switch, consider using a multimeter to measure your draw. If it's small, <800mA or so, consider adding a solar battery tender. Even a small 30W panel is usually enough to offset those kinds of draws.

Here's a pretty simple, top of the battery, disconnect switch, with no new wiring needed:
