This is exactly how my underbelly wad described to me. I have a contact at Jayco and I emailed him to get some clarification, too.
Most of my camping with the 23RB between November 1 and January 1 will be in climates with an average low temperature from 35 to 20 degrees F. If I can find away to keep water lines, water storage, and gray water from freezing at those temperatures I will be happy.
Here's what my "winter camping" notes include already:
* Hose for potable water tank is located under my couch. So as long as the temperature inside my RV does not go below 32 that line won't freeze.
* The gray water and potable water tanks are contained outside the RV under the frame BUT are enclosed in insulation and a barrier on the bottom of my trailer. Black water tank is also, but since I have a composting toilet in my bathroom, I don't use it.
* Adding some RV antifreeze to gray water tank will help prevent it from freezing. Draining it at night time is also advised and then adding antifreeze.
* Don't keep outdoor water hose hooked up at night or in lower temperatures unless it is a heated hose and/or has heated tape and insulation installed.
* Keeping an electric heater in the bathroom will help keep the gray water tank from freezing in lower temperatures.
* Block foam/insulation storage compartment doors + weather stripping.
* Block foam/insulation for windows + weather stripping.
* Checking with Jayco RE: whether or not the furnace blows head into insulated undercarriage to keep potable water and gray water tanks from freezing.
