Jim,

Your rig can certainly handle some 20 deg weather. What type of camping are you considering? Short or long periods in a single place? Campground with power or boondocking?

For short stays make sure your propane is topped off, if you are staying in a full hookup campground consider adding a small electric heater, get a heated hose unless the temps rarely go below freezing. For a short stay with temps just dropping below freezing at night you can often get by with doing nothing special other than running the furnace and turning your tank heaters on.

For long stays you might consider setting up a larger propane tank and skirting your rig.

This is just scratching the surface of actions you can take depending on how cold and how long you plan to stay. You will find several threads here with advice for different conditions.
