this is all new to us

Don't forget to lower the TV antenna before driving from campsite. Change lanes carefully watching out right mirror for small cars and motorcycles. Learn to downshift climbing or descending steep grades. Don't let following traffic goad you into going too fast around curves, pull over when safe. If any of your tires are older than 5 yrs by date codes, have them replaced. Have brake fluid replaced as part of brake system checkout. Have cooling system checked including all belts and hoses. Make sure that everything works and learn how to operate RV generator, furnace, water heater, fridge, and fresh and waste water systems. Make a check list of things to take that can't easily be bought along the way. When in doubt, get out and check clearance overhead and objects behind you. Your house batteries will last about 3 days if fully charged and in good condition. They are slowly charged by you engine's alternator while driving and by the converter charger when you are parked and connected to "shore power".
