traveling in cold weather

Most of your plumbing is probably inside the cabinets. At night
leave your cabinet doors open, also the bathroom door and cabinet.
The grey and black tanks should be okay at that temp as it takes
sustained freezing temps to freeze that large of a mass. We are
camping this weekend where the Sat. night temp is going down to
about 29 F. I think this will be our last camping for the year.

Have Fun, Brian

Get a service manual and look at where the pipes for your fresh water are. On our Winnebago they're all inside the coach, so as long as we keep it at 50F we're good.

We rarely are in sustained freezing temps, but when we are, the potable lines are blown dry and we resort to bottled water for everything (milk jugs of tap for the toilets work great). Not as worried about the waste tanks. They're below the floor, but there's enough room for ice to expand upward if we get to freezing more than overnight.

Temperatures 25-30F for a few hours at night, with 40-60 most of the day, have not been a problem for my rig, except that I'll be needing to buy LPG every 3-6 days. I know where my fresh water tanks and plumbing are located (all inside space heated by the furnace).

But my C is not a Four Winds, different manufacturers build C's differently. You need to know what part of the plumbing is heated, what is exposed, and decide what to do about anything exposed.
