A small electric heater in the wet bay and one inside in the kitchen/bath area will like work well. Open cabinet doors that have plumbing inside. Should be cheaper than running propane but is certainly a viable open as well.
Don't leave water in there and hope for the best. That can be a costly mistake.

Winter temps along the panhandle are not so much different than here on the inner coast of Vancouver Island. That's exactly what I do here, and have never had a problem.
I removed one of the access panels to the plumbing area from inside the cubby, and left the small heater run on medium full time. That space in my rig is vented to the living area thru vents in the stairs to the bedroom, and so gave a bit of heat to the rest of the trailer as well. That's assuming that you are plugged in to shore power.
