I spent many mornings listening, that is my biggest fear.
The cold is the biggest enemy, and the heat.
My rigs thermostat reads 39 degrees Canadian right now, after 40 it just displays HI. Without the AC one could not last long.
Inside all winter, outside all summer mostly.
In winter were ok with a ceramic heater and our Big Buddy propane heater turning the furnace on here and there.
So many challenges to rv living. When I first started I had no idea, it just all arrived and I dealt with it.
Its been one of my favorite challenges ever.
I would go for it, especially if your next to a house providing power.
Remember tho to chip the ice off the inside windows, otherwise it'll drip on your pillow.
