Kinda new to these things. Just noticed theres an air dryer under my cab by the tanks. Its the big black dome one, not the small cartridge looking one I saw on another thread. How do I know if its working or needs service? Never used one before, not sure what to do with it as far as maintenance. I've had this truck 5 months now and I never knew it was there, so I have no idea if any work has been put into it, or if it needs work. lol
