If you plan on freedom camping, your camper needs to be Certified Self Contained. How long you freedom camp depends on what facilities you wish to use in your campervan. The more equipment you use the quicker you will use the available charge on your house battery. To prolong your freedom camping experience, try to keep the fridge closed as much as possible. A good tip is to keep the fridge filled, even by using recycled bottles filled with water, and turning the fridge to a lower setting. Parking the vehicle in the shade can also reduce power consumption.
We recommend plugging in and recharging your house battery every second night at a powered site to maintain the lights, fridge and water pump.
