Need advice - How cold is too cold?
We have plans to go to a nearby state park this weekend. As luck would have it they're now calling for record low temps. Fri. & Sat. nights. Down to hi teens or low 20's. The furnace will be on so inside pipes should be ok but I'm concerned about the drains that come out under the belly. Will they freeze hard enough to break? I can drain the low point drains but we'll be using our own water supply so I can't drain the fresh water.
