Batteries dead in a week or less

Hiya all, looking for some suggestions on where to look.

We have a 2014 36CKTS. It is brand new, have had it for a grand total of 12 days. We picked it up on a Friday and went to an RV park with it. Stayed the weekend on park power and came home on Sunday.

Did a 2 hour drive home, parked it and turned off every switch we could find to include the master switch and the inverter switch. We then tested everything in it to make sure no lights could turn on to ensure power was off. Even checked the leveling jacks to ensure that they were off.

Went to put some stuff in the RV today and found that the power is completely dead. Not even getting a flicker. I did not have a multimeter with me to test the batteries, but I am going to assume that they are good since it is a brand new RV (albeit a 2014).

Any thoughts on what could be causing some kind of a power drain with the main power cut off turned off, and the inverter off as well?

Thanks, Rob and Lynn

The propane detector or the radio's memory can do that. Make sure you've killed the battery disconnect, or unhook the battery when putting it in storage to prevent that from happening.

Now, I'm not familiar with a Master Switch, so it might work like a battery disconnect, but if your batteries are dying it sounds like it's not really killing the parasitic loads

Thanks for the reply.

On this model, there is a master switch that is by the panel for hooking up everything (power, water, sewage, cable....etc). It is a 90 degree rotation switch that is on or off. When off, none of the stuff inside works.

The inverter cut off switch cut power to the jacks (hydraulic).

With those 2 switches off, I could not get anything to work at all (when I had power).

I could see a memory power for the radio and a propane detector bypassing those. That would be a irritating if you dropped stations every time you turned off power and probably spark customer complaints. And the propane detector would be an avoid lawsuit type item. But I can't see both of those coming anywhere near to draining 4 batteries completely dead in 7 days. I would expect that would take 2 to 4 months at a minimum.

Will probably install a true cut off switch in the near future that disconnects the batteries 100%. But, still hoping to find the simple answer as well.

X2 on the battery disconnect and not being familiar with a Master switch. My battery always went dead really fast until I had a battery disconnect switch installed.
Great choice for "Living within my means" and camping for one...

I assume you turned the master switch by the batteries back on

On some rigs there is a 'salesman' switch near the door also.
have you found one of those and turned it on?
