Off-roading refers to what you might call an afternoon adventure, maybe a whole weekend, if you’re feeling bold. All you really need for the trip is a reliable 4×4 and a tank of gas, or a fully charged battery. Bring along some snacks, a jug of water, and you’re good to go. Overlanding, on the other hand, could have you out there for days, or even weeks, with the key phrase being “self-sufficiency”.
