Ok sorry been working haven't had a chance to respond.
eubank very good document thanks so much.
I was hoping that being a new trailer it would help with avoiding freezing.
My dad has also recommended dripping the water.
I guess I have read somewhere that the grey and black valves could freeze, but I am pretty sure mine are not exposed so hopefully the central heat will keep them above freezing. The trailer is so new I don't really know much about it. We had a Hill Country 34BHR before and just got this one in October so it will be our first big trip. It stay at my parent's RV park in the meantime.
I am used the heat and trying to keep the trailer cool not the other way around! lol
