This has me wondering: Is it really that easy to get a vehicle registered and go off driving in it when you go to another country?
I mean, I have no experience other than what I know in the states I have lived in where you have to be resident and have a local drivers license in order to register a vehicle and insure it before you can drive it off on you merry way....I know there are exceptions for commercial and certain out of state registration situation when you have two residences, but out of COUNTRY registration????.....I would think some sort of rental RV situation will accommodate a person with a driver license from another country, but I'm not sure about BUYING and getting tags and driving off in just a day or two to process it all.
I'm sure knowing someone in the country you will visit could help tremendously.
Anyway, best of luck to the OP, if it can be done within your resources and time, then GO FOR IT!!
