RV's have parasitic draws you may not be aware of.
Things like Carbon Monoxide/LP detectors, Stereo/bluetooth units, condensation heaters in refrigerator doors/dividers, Refrigerator control modules, slide controller boxes, etc., etc with most of them not being able to be turned off. Also, if you have one, some newer variable speed water pumps draw additional current at times.
You didn't mention whether your lights are LED (hopefully they are) and you didn't mention whether your battery was fully charged when you left.
Did you run the furnace?
The water heater has a control module that consumes a small amount of 12v too.
How are you checking the battery? If using the indicator lights in the control panel that isn't a good indicator at all.
All I'm saying is so far, there are too many variables in what you've presented to say whether anything is 'wrong.'
