I have one in mine here in PA just doin tests when the truck is warmed up it blows nice hot air !(not road worthy yet)
Installation was very easy , you get a template for your 3 mounting holes and 2 lines ...the switch is very user freindly and the defrost vents mount right up to your dash..only thing with it is that you have to open an shut doors if you want heat or all defrost ...But it is a very simple clean unit .
