We travel from Connecticut to Florida each winter. we leave winterized. we have nothing running. Refrig is filled but not running until we hit the carolina's. we stop at truck stops for rest and sleep in the camper. we turn the heat on to get temp up to 60 or so. we use our toilet all the way down using rv antifreeze only. Once we are in warmer weather we de-winterize the unit, start the refrig on propane, and dump tank tank if needed. it has worked well for the past 5 years.
