Ditto on the temp tag from the Oregon dealer. I would think that they could do that for you. I flew to Michigan a couple of years ago and purchased a used Suburban from a Chevy dealer. He put a paper temp Michigan tag on the Sub. I made two side trips before I drove it back to Florida. When I got home I paid the sales tax and registration fee, and got a permanent Florida tag.
I did not even talk to anyone at Florida DMV before I went and got the Suburban.
