I believe that if its manufactured in Canada, you will pay your state sales tax(es) on it. There should be no import duty as it should fall under NAFTA. At the time of this post, you will have about a 10% dollar advantage over the Canadian $, so pretty good value. Most motorhomes are indeed built in the U.S., but there are still some, such as Triple E that are manufactured in Canada, and are a good unit.
