2018 Carbon 33 no lights inside

[Jofar33]

Hi folks, we just got this toy hauler a few months ago but haven't used it yet due to the lock down.
Brought it home from the storage yard today, installed fully charged battery and the front jack worked fine. At home, extended all 3 slides out and they worked fine. No inside lights???? Raised the bed in the cargo room ok.
No radio, no tv and refrigerator lights not on.
Reset all the breakers and fuses look ok---no sign of burnt fuse.
Anyone have this happen and what the problem might be?
This is a 2018 model and like new...very little use.
Thanks for any leads you may suggest in finding this problem.

On many trailers, the slides, landing gear and tongue jack (travel trailer) do not "get cut off" by the battery cutoff switch... In other words, that equipment is directly wired to the battery not through the BCO switch. You might check your BCO switch to see if it is turned on. All your lights, radio, refrigerator are wired into the BCO switch...

The television is probably 120 VAC and will not work unless you're either connected to shore power or using an inverter to power the TV.

OK....found my problem. the battery disconnect switch inside the storage compartment was turned to the OFF position which is misleading--it should say battery power to cabin... on---off...new labels will be installed there.

It can be confusing. It is a cut off switch:

ON: power is cut off so ON is OFF
OFF: power is going to trailer so OFF is ON

Sort of like the switch on the water heater, it’s upside down so ON is OFF.

That's opposite of the cut off switches in my current trailer or any previous trailers. ON is connected, OFF is disconnected. Easiest way to tell for sure is if you can pull the red handle out the battery is disconnected.
