Off-Grid Prepared
Are you off-grid prepared? Seriously, if a natural disaster occurred, do you have 3 days of food or are you ready to possibly live in your vehicle? This website is my project. Watch my mistakes or successes in building an off-grid vehicle. My selection after my exhaustive search is a 2002 Honda Odyssey. Check out project steps for everything needed to install solar panels on an any vehicle. Solar panels charge the battery system, so I can run a refrigerator, lights, and charge any devices. I also use my van as a camper to test everything in a real life off-grid scenario.
Even though you should have 3 days of food. Really you should have 2-weeks of food and water.
