How does USA car insurance works for a European traveler?

Next summer I've planned to go the States, start somewhere in Florida, buy a camper and travel around the states for 5 months. To be clear: I'm a 22 year old guy from the Netherlands, with a Dutch driving license (I'm able to get an international driving license).



Ofcourse I need to get insurance for this camper, which I consider to be somewhere problematic since:

- my age (23 when I get there)

- no postal address

- no social security number

- no family or close friends in the area to work things out with

- want to be able to travel through all of the states (each state having different laws)



How does this work, am I able to get an insurance for this?How does USA car insurance works for a European traveler?
Buying a vehicle that you intend to keep for less than 6 months is one of the worst financial decisions that you can make in the U.S. When you buy a vehicle and then sell it less than 6 months later, you typically get at least $5000 less for it than it cost you, so you are effectively paying more than $1000 per month to have it. Insurance for a male person under 25 in the U.S. who has not previously had a U.S. license or U.S. insurance can cost over $1000 per month, so we are looking at a cost to you of at least $10,000, plus maintenance and repairs.



You might be able to rent a camper for much less money.



The postal address issue is easy to address. Rent a post office box.



Only citizens of the U.S. and Canada are allowed to visit the U.S. for more than 3 months at a time without a visa. Dutch citizens who are staying more than 3 months must get a visa from the U.S. government before they arrive in the U.S. Ordinarily, you might be able get around that by crossing the border into Canada after 2 and 1/2 months and immediately returning to the U.S. However, the vehicle purchasing/registration/insurance etc. may create a need for you to have a visa even if you are not staying more than 3 months at a time.



Even if you have a visa, the government officials at a borders and airports may deny you entry (or re-entry) if they believe that you intend to stay in North America permanently and not to return to your home country. Since EU citizens normally do not buy vehicles in the U.S. unless they intend to stay permanently, if you purchase a vehicle, leave after 2 1/2 months, and try to re-enter, it is likely that you will be suspected of planning not to return to the Netherlands, and not be allowed to re-enter.



An international driving license is not valid in the U.S. You can drive in the U.S. only if you have a valid license which is not an international driving license. However, if your Dutch license is not in English, then getting an international license in English is helpful, because it will allow the police (who cannot read Dutch) to know what your Dutch license says.



U.S. insurance is valid only in the U.S. and Canada. If you are going to cross the border into Mexico, then you need to buy insurance for Mexico.



Finally, you do not want to arrive in the summer and start with Florida. If you arrive in the summer, then you want to do the states where the roads are dangerous in the winter (because of snow and ice) first, before the weather gets bad, and save Florida for the end.
