During the February arctic blast in Texas we reached -3. This temp is not good for an Outlaw RV. We had some freeze up of 3 areas.
The water tank froze. It thawed without any issues.
Second was the Shurflo for the water pump. The plastic base broke due to freezing. See the Photos below:
The replacement part is shown below: you cannot buy the plastic base.
The second part to break was the water filter housing.
I had to purchase a full replacement kit as the individual parts were very hard to get due to the Freeze.
The RV had the heat on and the Shurflo for the water pump and the water filter both froze and broke.
Advice for the future is to place a heat source in the water filter area and by the actual water tank.
