coach battery

I have a 2013 Four Winds 22E and just did a 3 day dry camping trip. We use our refrigerator using propane. The coach battery drained in 8 hours. We didn't use lights or pump. I removed the fuse for the radio/rear view camera which is on when the coach battery is on. I would start the generator using the chassis engine and charge the coach battery for 30 minutes, then get another 8 hours. I'm told it should support basic use for 24 hours. Any ideas what is draining it? OR how do I track down the culprits? Thanks.

sorry, i don't have direct answers for you.
Are you sure the battery is good?

Wondering.... do you have the pioneer radio? I have that and couldn't figure ot how to turn it off.
posted the question here and someone explianed how.
Sorry, don't have time to find the link just now but you could search for it "pioneer".
The lights go out but I'm still not 100% sure that is is OFF.....

I have asked Thor for a schematic to help understand how my '13 model is wired, but don't have it yet..... hopefully when i get it it will help to clarify what needs to be done to isolate parisitic draws.

Yes. I have the Pioneer radio with rear view camera. It is powered from coach battery and stays on while coach battery is connected. I just pulled the fuse from the DC panel to cut it off.
I plan to pull the coach battery and have it load tested at local auto parts store.
