I've camped in a class C in winter with the FW tank under the bed and the holding tanks exposed for weekends without problems by dumping antifreeze in the holding tanks. Did have sewer line freeze up once but it thawed when temps got above freezing during the day. Make sure tanks are empty before you dump in antifreeze so it can go down the sewer line to the dump valves. As long as I kept it warm inside, the FW system worked. Your mileage may vary?
