This is based on your campground and actual campsite. If you camp in an RV park with water and power, we will gladly hook up the trailer to their system. If you are “dry camping” without standard electric or water hook ups, the trailer is self-contained and carries approximately 40 gallons of fresh water. The batteries operate your lights and some electric appliances, such as the heater fan. The batteries are charged during the day with large solar panels. This should eliminate the need to exchange your batteries during your stay. The stove, oven, refrigerator, and heater operate on propane gas. The propane tanks on the trailer are generally sufficient for a 10+ day stay. The microwave and outlets will not work without electrical hook ups or a generator.
