If your Freelander motorhome does not have tank heaters is it ok to use in late November in Pennsylvania when night time temps go below freezing? Thank you for help.
Depends on how cold it gets. You can always put RV antifreeze in the gray and black water tanks to keep them from freezing.
Your main problem is going to be protecting the water lines in the walls from freezing. Winterizing and using bottled water should protect you if the temp gets much below freezing and stays their during the day.
