The problem is licensing the camper in the state of Washington. As far as I know Washington, Oregon, and Idaho are the only states that require a camper to be licensed. It doesn't make sense to me but it is the law. In order to do this I have to have the correct paper work from both the US and Canadian Customs showing when and where the camper was imported and that it meets DOT requirements. If I didn't need the paper work I could do as many have suggested and just hand them my passport and drive across. No problem. If I'm going to drive it around legally in the state however I must get it licensed and they will then issue me a title. Just thought someone else out there may have done this recently.
