Edinburgh in zero temperature

[Yorkshireimp]

Quick question for all the seasoned travelers, we are going to Edinburgh this weekend for the Christmas markets,and the forecast for the temperature could be down to - 3 celsius, we will be off grid but I have gas heating, solar, inverter, and 240 aph leisure batts. My question is do I fill my water tank full of water with the risk of it freezing? As I know the inside of the van will be fine, but my water tank is outside underneath the vehicle, it is insulated but will this be enough to stop it freezing any suggestions would be welcome as I have not been away in freezing conditions.

I'd fill it, in a heated van I doubt it would freeze.
The pipes might be more vulnerable if they too are external ?

I would think if it’s full and well insulated it would be fine, in our first van which was an elldis we managed-9, the only thing that froze was the waste pipe. I started leaving it open with a bucket underneath, this save any water lying in the tank. In our PVC we stayed at glenshee ski resort at -15 with no issues, tanks were onboard. Now the tanks are in the floor and heated by the ALDE heating.

We stayed on the South rim of the Grand Canyon where it was -15. Our tanks didn’t freeze and there were campers in tents next to us !

Thanks for your response, it’s a 2001 autotrail main water tank has insulation and the pipes are mainly internal I have had a bottle of water inside the van over the last couple of days just to see if it would freeze without any heating on and it was fine, just wanted to ask as I know it’s a difficult one I will go with a full tank and hope for the best
