canada customs policy on buying airstream in states

[annw]

I have been finding it difficult to find used airstreams in vancouver where i live. There aren't many around and only one dealer in BC that sells them, and according to the sales man they are lucky if they sell a couple a year. They are quite expensive and used ones rarely come up for sale. There in one 28 foot international ccd 2004 for sale, but it is larger than i would like. I''m leaning towards a 19 or 22. 25 foot at the largest. Any information about buying a trailer in the states and bringing it across the border into bc would be greatly appreciated. My spouse thinks it is too much hassle and will cost just as much in the end as to buy one locally. He may be right, but the type of trailers i'm looking for seem to be more prevelent in the states. thanks again for any help on this topic.
