Trade-in in U.S.?

[TimnJo]

We plan on going full time next year and as a result are looking for a new (to us) fiver.
We're having trouble checking off all the must-have and nice-to-have boxes in the units around here and even across Ontario and Quebec.
So, with many more to choose from available to the south of us was wondering if anybody had any experience trading in their unit on a newer one in the U.S., and if so would they do it again, how difficult, the legalities etc.

Thanks in advance,

Tim & Jo

Most of the dealers know all the paperwork involved.
Check Canada Customs for all the legalities and time frames.
