should I fill water tanks in Freezing weather

[msboriken]

We're leaving for Texas after Thanksgiving and temperature will be around 15F degrees. Have a 2015 Montana 5th wheel. Should I fill water tanks or wait till we get to warmer weather?

I hope your wrong about the weather .... but if I thought it was going to get down to 15 degrees in Portland I would drain everything, blow the lines, and carry a few jugs of water to get me to warmer weather. Just my 02 (just winterized the rig because its' suppose to get in the 20's in Portland).

I would definitely wait. Use a couple of gallons of bottled water kept inside, and keep your waste water from food and washing to use as flush water mixed 50/50 with antifreeze.

If you dump a gallon of RV antifreeze into the black, then use 50/50 to dump for a couple of days until you get to the mid 20 degree temps, you will just be so much safer and less worrisome.

yep, I'd take a few gallons in containers and head south.

Is the water tank in a heated area of the rv? If so, filling will be just fine. If it is NOT or is exposed, I'd wait.
