One night running the heater and blower
I'm not sure what battery I have on the camper but I am sure it has the original battery (I'm at work or I would go look). It's a 2017 Cruiser RV - MPG 2400BH and has a 30,000 BTU heater. We have no...

typical furnace draw is 8-10 A. at 50F my guess is that with the thermostat set to 60F, yoau might have 4 hours run time on the furnace overnight, more likely 2 hours. Thats between 16 and 32-40AH, about 50% or less of a 12V battery. you will likely make it.
FWIW In our 35ft trailer at temps in the 40's at night I set the thermostat at 45F and the furnace does not even come on. It will run for 2 hours or so in the morning to warm up the trailer.
For us the furnace is noisy enough to wake us up when it cycles, so unless it gets real cold it doesn't come on at night.
As a comparison I have 440AH of 6V batteries. We can dry camp for 6 or so days running the furnace as needed in colder weather, (2-3 hours day on teh furnace) along with a CPAP, and lights and occasional TV and using the microwave on inverter to heat vegies etc. before the batteries are at 50%.
