Mystery Draw! Driving me insane

[TahoePowder]

I have a 2022 Jayco 24bh TT. Soon after purchasing, I swapped the battery for a 200a SOC mounted under the bed with a victron monitor. Never had any problems with it. A few months ago I went to check on the trailer at my storage and it was completely dead. It has a solar package and always keeps batteries topped off so I thought it was weird but was busy and left. Next time I went back everything was completely normal again.

I’m currently camping. All was good night one. Woke up this morning to our battery at 6% remaining life. Been running the generator on and off all day and the battery will not charge. My victron shows I have a draw of around 10.8 amps. I turned off every single thing in the entire trailer. Turned off every single breaker. Every. Thing. Is. Off. Still have that draw reading on my Victron. Anyone have any idea what could be going on here? Might have to leave our trip a day early because we’re at boondock campgrounds and there’s time limits on running generators.

Some guesses-
Does the Victron show a charge current when your generator is running? If your battery is lead acid and left uncharged for a while it may have expired.
Not sure if this is a typo, but pull fuses, breakers are for 120vac.
A 10A discharge is substantial, check the brake's breakaway switch. IF your RV has an inverter, check that also.

Agree with ARoamer, breakers will have no effect on 12v power draw, they are only controlling 120v ac power. First thought is that is a VERY large draw for a 12v system in a trailer. Not many items should/could draw that much power without a problem. Place to start would be to pull each fuse until you find which circuit has the current draw and then troubleshoot from there.

Do you have an inverter that takes 12 volts and turns it into AC/110 volts for appliances? They draw power and possible it is being used somewhere. Not switched thru your power panel.

On mine and many RVs some 12 volt items are not affected by the power panel such as the LP/CO monitor and possibly other items. They should not draw 10 amps so probably not the problem.
As above, if your battery is lead acid having it dead for long may have killed it forever.

Also, have you checked all connections for corrosion?
