Welcome to Canada... land of death and taxes! My signature truck options over and above the Longhorn package (which includes pretty much everything you could ever want) were T-case skid plate ($75), sunroof ($1250), 730N media ($500), BFG Rugged Terrain tires that I promptly got rid of ($300), Federal Air Conditioning Excise Tax ($100), Destination Charge ($1400). Base price was $70,440. Price with options $74,065. At the time the special of the day was "No charge Cummins". (don't forget the 5% Federal Goods and Services Tax).
I paid $59,900 which included a 5th wheel hitch installed, vent visors, mud flaps, box cover. All in all a very good deal (where I come from). My wife was the salesperson and this was staff pricing. I don't think it gets any better than this.
This was last July that I bought my truck, but considering our dollar is par and diesel in my area works out to $4. 73/US gallon, I say enjoy your pricing! I would gladly pay the equivalent of your US sticker prices without getting a deal!
