I am curently in the Seattle are and am going to leave my trailer for 3 weeks. It has been getting into the low 30's high 20's here in the early morning. Do I have to fully winterize? I was just thiking I would drain all of the holding tanks and drain the lines and leave the faucets open in the trailer to handle any expansion of any water in the trailer that may freeze. I was also planning on leaving the forced air heater on set at 42 degrees. Does anyone see a problem with doing this for just.
