We saw that however you need someone to give it to you . For some reason bringing in a trailer purchased from another country was a big problem . You are importing a trailer hence all the forms .

As I said I would just have my papers as the highway patrol told us to have , and go to a small DMV right when I get into California and get it done . We didn't fall off of a turnip truck and having lived awhile do try to get all our ducks in a row . Pat
