Winter Camping
I have an ACE with an outside kitchen. The pipes are very close to the outside and need your attention.
First, get an indoor/outdoor thermometer with two or three probes so you can monitor your outside bays. This will go a long way to sleeping well.
Like others, I place foam pipe insulation around every pipe I can access. Some places I don't tape it so I can access valves.
Since you have a 110 volt outlet in the outside kitchen, do what I do and put a plug in thermostatically controlled heater. This makes me sleep very well!
I also put one in my main plumbing bay as the pipes go very close to the outside and I don't want them to freeze.
I camp all winter in temps to the low teens and since doing these things have had zero problems.
