Winterized Usage

For freezing weather camping, we used an 8 gallon Hydroller watter carrier purchased at Walmart. We moved that between vehicle and R-Pod. We did not have any water in the tanks to start and carried a few gallons of RV antifreeze for flushing purposes. We also put some down the sink drains to help keep the gray tank from freezing. We camped in temperatures in the low single digits with significant wind chill. When we got down far enough south that I thought it was safe to do so, I put water in the tank and flushed the RV antifreeze out of the pipes and changed the bypass valve so we could have hot water.

On the return trip across Texas, we did encounter freezing temps and the pickup line from the water tank froze. It did eventually thaw with no problems. Other than that, the interior stayed warm enough so that we did not experience any freezing of the interior lines.

If I were to do this again, I would make a way to shield the water tank pickup line and use some spray foam insulation. I think that would be sufficient to keep it from freezing, even if we do get a hard freeze for a couple of days as it would take a while for the tank to cool enough to freeze. If I were really worried, I would heat some water and add it to the tank periodically also. Some have changed the plumbing to be able to circulate hot water so as to have instant hot water. The return lines go to the water tank so that water isn't wasted. This also serves the purpose to help heat the tank to prevent freezing. I have been thinking of doing something like this as well as modifying things for hydronic heating.
