David,
I moved your topic as it really doesn't list a trailer
for sale, and is more of a general chat kind of question.
The relative rarity and the construction of
Bigfoot trailers cause them to be in demand. Demand, plus the high costs of buying new (a new 17.5' Bigfoot will run $32k USD) keeps the used prices higher than some of the other brands. Provided that the trailer needs nothing in the way of repairs, $12k CAD is probably not an unreasonable amount for a Bigfoot 19' trailer.
