We like to think that any RV is capable of living off-grid as long as you consider power and water as your most important necessities. If you are fully supplied in water, and even consider carrying additional water containers, then you can last weeks off-grid. And if you equip your camper with solar panels and an inverter you can have virtually unlimited power. Of course, you’ll want to know how much food you can store away. And keep enough fuel to take you wherever you’d like. Otherwise, truck campers are great for off-grid exploration!
