5 amp/day elec drain

I've always suspected our used RP used power too quickly.

It wasn't until I installed a Lithium battery and charger, Renogy meters, etc., that I could  see what was going on.  

I'm drawing .35 amps on #4 DC circuit (Bath Lights, Stereo, Fan).    That's about 3.5 amps a day.  5 Days = 17.5 amps, 10 days = 25 amps.  Not funnily when your pushing miles cross country and staying at truck stops or your new car breaks down and your stuck in a Car dealership storage lot for 6 weeks, etc. lit we were.   We called that our test run.

IS THIS A KNOWN PROBLEM?

Things I tried:

Stereo was already disconnected.  We don't use.

Bath Light was switched out to a plain on/off LED. (No Change).

I can try unhooking the fan... but I don't see how that could be the problem.

I actually have trouble shot a bunch of other problem in the major Lithium power conversion and now have a very respectable system or so I told by my buddies... but this #4 DC Circuit current drain has me baffled.   

IS THERE SOMETHING ELSE ON THAT CIRCUIT I'M NOT AWARE OF...???

Lets say I've gotten to know my R-pod very well.
