RV FEATURE PUTTING ALL OF THIS TOGETHER How does all of this information apply to a real world situation? Acknowledging everyone is different, we can look at a typical situation to see just how much power we might consume. You arrive at your campsite around midday after a three-hour drive. Thanks to the Anderson connection between your caravan and tow vehicle, the RV’s batteries are fully charged. As soon as you unhitch the van, your batteries are starting to discharge. The compressor fridge starts working immediately. To keep everyone entertained during set-up, you turn the stereo system on and play the music through the external speakers. Everyone is using their mobile phones, calling family to say you’ve arrived safely, checking social media feeds, taking photos, etc. They’ll need charging later in the evening. Before bed, everyone’s a bit dirty so everyone has a shower. The pump is running again. More lights in the ensuite are turned on. The toilet gets a workout, which means flushing and the water pump running. Everyone goes to bed so the TV and lights are now turned off. But someone turns on a bedside lamp for an hour or two to read a book. All the electronic devices need to be charged so every available USB port is powered. Dad has sleep apnoea so on goes his CPAP machine. Finally, all lights are turned off and everyone is asleep. The only power use comes from the fridge and dad’s CPAP machine, which will operate for the next eight hours. Later, the radio is off but you’re inside watching TV. The dishes need washing so the water pump runs to fill up the sink. It’s getting dark so you turn on the LED lights. After dinner, half the family sit outside so on go the outdoor floodlights, while the other half stay inside where it’s warm thanks to the gas heater, and continue watching TV for the next three hours. Running all of these lights for three or four hours will drain a lot of power from the onboard battery. 22 \
