You don't see these units on the road here because they are too expensive for the Canadian market. In certain regions of the US there is 0% for 72 months or $6000 off. Couple that with much lower MSRP and buck less a gallon gas and they are doing well relative to the competition. They tow 10,000 lbs. and unlike Canadians, Americans have big toys.
What many here forget is the Canadian market, in context to the US market, is an after thought.
