Paul, the dryer is to collect the oil from the compressor also they not just for freezing weather
Yeah I follow that, but if your blowing the tanks down regularly, etc...would it really matter? IOW, I'm looking for someone to convince me that adding a $200 plus air drier plus all the hose connecting and wiring is going to offer me something more than something else to break. Will the brakes chambers or other brake parts last longer?
My understanding of the drier was its primary purpose was keeping the system dry of water in freezing environments. I will likely have to have a gun pointed at my head to ever drive anywhere below 50*F.
