This morning while enjoying a nice rainy day inside a cozy RV, we did hear a cracking noise coming from the bathroom, and here is the result. Fully level and no movement.
We don't run the heater during the night. This morning it was 43 dec inside (dogs and humans love sleeping under warm blankets) the coach before starting the heater to heat up to 68 dec. Seems like an issue with uneven expansion rates.
Question: Is that mirror clued and screwed to the door and should it be removed before going back on the road?
