I bought from the US, new saved $15,000 over what any dealer was even willing to 'bend over' to give me the best price, of course dollar was close to par then.
Cost are transportation if you are getting delivered, brokerage fees to get across border ( hire a broker to facilitate, or have RV dealer set up) and inspection for canadian certification.
Many dealers WILL work on your unit, just may not be at front of line, do not beleive what is being sadi about that. Or find an independant RV repair only shop that can get factory permission to work on your unit.
