I believe a shunt will have a tiny draw as well, mine is showing a tiny draw when the battery switch is off. I need to investigate further as my Li battery is discharging faster than 1%/month. The shunt does have a power wire that is always connected.
I installed an Anderson connector that allows me to easily remove my Battle Born 12V lithium battery from my trailer and use it for other purposes (or to charge it) when I’m not using my trailer. For example, I can bring the battery inside and use it to power a Power Station and extend its operating time by feeding it through tie 12V input port which will accept about 100 Watts. I’ve also used it to run a trolling motor. It feels much better to find alternative uses for these expensive lithium batteries which will difficult to cycle enough in an RV to reach their multi thousand cycle lifespans. BTW, I’ve left my battery sitting for many months and never seen it drop to a dangerously low voltage.
My 2015 Coachmen has a separate inline fuse that runs the fridge "eyebrow", the LP/CO detector, and the slide relay. Using "Battery Disconnect"...doesn't!! So, switch off, fuse pulled, Battery Tender on, good for winter!
Every modern RV I have looked at connects the detectors around the battery cut off. That makes me think that it may be some sort of RVIA code or recommendation. Doesn't really make sense but .......
On my 2011 Winnebago the propane only works when the propane switch is on, which means when the battery switch is off there is no propane, so when the battery switch is off there is also no propane detector as it is not needed when there can't be propane flow.
Have you checked the power supply to the LP detector with the propane switch off? Or does the green power light go off? I assume you have an under carriage tank with a propane on/off 12v DC valve. ie Class B/C?
Many of the common CO/LP detectors for RV's are rated at 100 to 120 Ma. I am very happy that the one that came from the Jayco factory in my TT is rated at 17Ma.
Also, this is true for all RV's, not just Airstreams. The battery disconnect switch (OKA The Salesman's switch) does not turn off all 12v DC supply to the coach, ie power to LP/CO detectors!!
On my 2018 Thor Vegas, the coach batteries disconnect switch (in this case, called the Use/Store switch) does indeed disconnect power to the LP/CO detector when in Store mode.
Yes, in my 2001 Newmar Mountain Aire there is an "LP" switch in the main control panel. Its purpose is not to control the propane but it turns OFF the 12v DC power to the LP Detector when in storage! The RVIA has since outlawed such a switch so you will not see it in younger RV's. See my previous comments on the initial thread by Mike.

I have lead acid batteries and use a disconnect on the negative side when RV is in storage. I’ve never had a battery discharge issue while in storage.

It is not just winnebago, quite a few of the battery disconnect do NOT disconnect everything and leave propane detectors on.

When the propane switch is off there is still power to the propane detector. When the battery switch is off there is not. Class A with ASME tank.

Makes a real difference.
