We have 4 holding tanks in our 3711fl. The fresh water up front, the galley in the middle. The grey and black in the rear. We have not used the tank heaters at all thinking that the furnace would protect all tanks in the underbelly from freezing. I assumed that our 2016 has the arctic package as did our last 2010. Are we wrong? We live in the Florida Panhandle and it gets in the 20's here some nights. We always empty our black, galley, grey holding tanks and flush the black after every outing but leave about 2/3 fresh water in the tank. Are we safe with what we do?
