I did that with my camper.
If any of you all have an RV, make sure to check the water lines after the weather heats up. Before you take a trip.
You want the main house water OFF, before any thawing. Use a buddy system. One at the main valve turning it on just the smallest bit, while others listen for leaking, spraying sounds, looking for sheet rock going wet, wallpaper/paint bubbling/bulging. Best to heat the house up fully so all wall pipes are thawed before checking.
