>>2828580vanlife will to some point get cheaper the more money and effort you spend on the initial setup. and most instagram vanlifers spend all their money and effort into making it look like a wooden cabin and then suffer from poor milage, crap electric systems and such, but they dont care they only sleep in urban parking lots anyway. if you look at overlanders, they have no limits on what they spend on solar, lifepo batteries, charging setups, various types of cooking gear, fridge/freezers and such. but their interiour look industrial because bringing the whole lumberyard into your van increase weight = shit handling and mileage, and they usually go for reliable fuel sippin diesels. they build their rigs to spend months in places where you can barely get fuel so better be self sufficent or survive on very little.
so with the latter, you can definetly make it with only the cost of fuel (depending on how much you drive around) and cost of food (raw products), the first one it depends on how many starbucks coffes and foodoras you have each day.
