Your air conditioner uses 12V too. I suspect your converter has failed or the battery has a shorted cell.
How does an air conditioner use 12v? They are powered by 120v AC power and most thermostats are powered by little AA/AAA batteries.
Most thermostats are not powered by AA or AAA batteries, and even when they are the HVAC is still controlled by 12VDC because the furnace doesn’t use AC power and the thermostat controls both.
OP is having issue with the A/C and low battery voltage.
No need to cover all RVs until the OP has the issue resolved.
Maybe you should address this to the previous poster who believes RV thermostats run on small batteries rather than the person who pointed out that it was likely a 12V battery problem.
