I traveled the US in my car last year. I gotta say it's been an adventure and one of the most beautiful places I've ever seen( been to 32 countries).

For two people the average came out to be $2500 a month.

Sometimes we camped, slept in the car or booked a hotel. This came out to $0-$150 a night, depending.

We cooked most of our food, Mexican ingredients are widely available everywhere and gave us the most flexible/healthy combos. We would try local delicacies in every State, and in the South I went over my budget with the Cajun/Creole/Soul/BBQ options.

gas came out from $300-600 depending on how much we drove. This was last year

Misc expenses added quickly as I was addicted to Bison plushies, stickers and national park pins.

The most challenging thing was dealing with the weather. I would experience a different ecosystem every other day, some days New Mexico was colder than Siberia, other days I had to deal with wildfires, strong winds, snow, heat, you name it.
