It's winter and for many of you, the RV is winterized and stored somewhere. For the rest of us in warmer places, the RV is parked nearby and not used as much.
Just because you're not traveling doesn't mean the RV will be all right just sitting there until you want to use it. Whether it's a trailer, fifth wheel, tent trailer, truck camper, folding trailer, or motorhome, some kind of moisture barrier should be placed on the ground under the RV. Your truck camper is probably on some kind of platform or pallet. If your RV has tires, you can purchase inexpensive plastic placemats to put between the tires and the surface they're resting on: dirt, gravel, asphalt, cement, concrete, etc. Use your jacks to raise the rig slightly so all the weight isn't resting on the tires. Flat spots could develop on the tires from sitting.
If your RV is nearby and you have an electrical connection, keep it plugged in. Use the refrigerator on propane to keep critters, especially spiders, from setting up housekeeping in vital areas. Spiders love propane. Your water heater should be drained (stand back because what comes out will be ugly and smelly), filled with fresh water and turned on weekly to let it cycle through heating your six or ten gallons of water. Run a water hose to the RV as well and check your connections for any leaks in the faucet, sink, shower or toilet.
Your motorhome should be started weekly and ideally driven somewhere. It's meant to move so just running the engine is not enough. Drive it around the block or to the grocery store, park or shopping center.
You might also consider using the RV as a private office to escape the hustle and bustle of the holidays. Watch your football games or read your favorite novel.

Remember the RV!
