How long does this take? How old are your batteries? How many time have you run them dead? All of these questions will be helpful to know what to tell you. Assuming that the answers to the last two questions are not very old and just a couple of time I would suspect so-called phantom draws. There are things in your RV that don't shut down when you hit the battery disconnect switch. If it's taking a couple of weeks this is likely the culprit. It it's only taking overnight you need to look for something else. The solution in both instances is to disconnect one of the battery cables. If this is the route you take you may want to look at your inverter/charger manual to see which cable to disconnect. Some inverter/chargers want you to disconnect the positive cable and not the negative one. Good luck.

Get a clamp on DC ammeter. Amazon has decent ones from Klein Tools for about $80.
Measure the current by putting the meter around the negative battery lead where it connects to the battery. Measure the current. Then one by one, remove each fuse at the converter panel and see how the current drops. Then at least you know which circuit is causing the problem.

80 bucks for a clamp on meter ?
May just as well buy a battery monitor for less and have all of its features.

Doesn't exactly fit the below $80 criteria posted above, but Vitctron's battery monitor would be a good tool to have.

I like my $44 AiLi monitor. Knowing what is going in, and coming out is a valuable tool. It will help determine if it is something sucking the battery dry, or if your battery just doesn't have the oomph it used to have.
Sitting at home mine using about 3/4 of an amp waiting for me to turn something on.

Smoke detectors?
Do you have an inverter?
How long does it take and is this a new problem or has it always does that?

If you have an inverter, which I suspect you do, make sure it is turned off. I had all (4) of my coach batteries go dead, bought (4) new ones and they were dead within 6 weeks. It was then that I realized that the inverter had been turned on the entire time.
