importing camper from B.C.

In early 2013, I bought my 2008 Bigfoot in BC and drove it across the US Border at Blaine on I-5. Just had to have a copy of the invoice with me. The discussion at the border was very cursory. Much easier than I'd anticipated. I first contacted a customs broker who suggested I should phone the customs post directly, which I did. US Customs were easy to get a hold of and told me what I needed to know. So I did not use a customs broker.

Easy peazy.
