DNs that are American that stay in America.... don't call themselves digital nomads. They just call themselves remote workers and move somewhere.
Or vandwellers. Or tiny house livers. Or homesteaders. Or whatever other term.
Like I'm in the US living extremely cheap in a camper I built that I park on some land I own in Maine. Super low cost of living and I mostly just work and grind my business.
But moving to Puerto Rico soon (also America) because it makes more sense for the business.
When I'm ready to travel more, I'd love to get out of America more. The culture of America is pretty ugly. And most places think mayonaise is the height of flavor / seasoning..... lol
In general you pay more for everything in America....while getting less. I've paid 20 dollars to get sad overcooked and bland chicken on rice..... that type of money could have gotten me a feast with flavor elsewhere. But in America the slogan is "fuck you, come again".
If you had a camper or something and were going to be staying at truck stops and walmarts, then you would be fine.
But if you want to pitch tents at camp sites, it's a lot harder.
And gas really adds up.
If I were you, I'd build a DIY camper you could pull behind your car. Or try to get a truck you can outfit for sleeping and prep to do the trip in a year or two. But you're probably going to need a bit more of a budget for it. Especially if you haven't factored in your vehicle yet to costs....
