I do not know your coach. This means the first question is how exposed is the plumbing and tanks? Underneath the coach, what pipes and tanks are exposed to the elements? Are the pipes and tanks enclosed in the coach basement?
If the pipes and tanks are exposed, consider using RV anti freeze (the pink stuff). Check the bottle for proper dilution.
If the tanks are enclosed in the coach basement, does the coach furnace provide heat to this area? If so, nothing more needs to be done. If no heat is provided to this area a small amount of RV anti freeze is all that is needed. This small amount helps keep the tank valves from freezing.
