It's a gamble. I'm in a similar boat..... We want to camp one more weekend
also and I'm holding off winterizing the water lines as long as possible.
Lot's of variables-- If you run your water heater once a day it should
not be a problem. I'm gonna make sure my holding tanks are empty in
the mean time but plan to use them when we get to the CG. I may blow
out the city water inlet just because it's sorta hanging out there on
the wall exposed. I'd hate for the check valve to freeze and break.
When we camp we won't be on city water so the water tank inside my
pass thru storage should be ok for now.
27 degrees can freeze pipes if they are exposed....
Another option is "dry camping". Go ahead and winterize the water
We have 2 blue water jugs. Use those
for teeth brushing and washing hands and dishes if necessary. Use paper plates and
avoid dirty dishes as much as possible. Put a couple milk jugs of water in
the shower or bathtub and use those to flush the potty.
If I'm really worried and it's gonna be several degrees below freezing, we use the CG toilets (even if they are flushless vault
) If there is any middle of the night trips to the trailer bathroom
or gray water from washing or brushing-
I can empty the holding tank into a bucket and dump that down a vault
toilet sometime during the day.
This dry camping is not our favorite but if the weather is dry and sunny and
crisp we enjoy hiking and campfires in the woods! My methods above are
easier for us because there's just 2 of us. If you've got a trailer load of kids it gets more
