Test fit your tire chains before you go. Need a set for the primary drive axle and one trailer axle. I use link chains on my truck and the light cable chains on the trailer. These would just be in case you get into an unexpected storm. Generally you would wait for the roads to be cleared before you roll. Go slow and enjoy the white Christmas.
Check your propane early each day as some places close early. I have been low and hoping to make the night when all propane was closed by 6PM because the guy that does it was gone for the day.
Your water supply hose may freeze overnight so just fill the tank and disconnect the hose.
Your slide top may accumulate snow and turn to ice that should be removed before you bring it in. If you can bring the slide in you could avoid the hassle.
Most likely you will have no issues and a great time.
