Canopy for 6'4" Dodge Box

This canopy is in very good condition. New canopies seem to cost around $4000 plus tax now, so I think this price is fair. There is a sliding window on one side and a full width pop up window on the other side for easy access to a slip tank or whatever else you need. (I'm also selling the slip tank that's currently in the truck). It is currently on a 2007 Dodge 3500 Megacab but will fit on other trucks too. The inside measurements for the box rails are 63" wide and 6 ft 2 1/4" front to back.
