Extended season use of TT near freezing temperatures

If you have a 12V compresser blow out the water lines with air and make sure that you dump the tanks before heading home. Start with the cosest to the city water hook up and blow the line until you get nothing but air, close the valve and move to the next valve. You don't need much air pressure to get the water lines empty. Don't forget to drain the fresh water low drain point.

I have been blowing out the water lines for years now and the only anitfreeze I use is what I pour down the drains.
