[77newell]

I don't know the vintages when Newell used the "maintenance free" dryer that looks like a vertical finned cylinder. My 93 coach came with it and based on the vintage of the dryer it had been installed by the factory. The drive from Texas to Michigan produced a bit a water from the service tank drain and from one of the brake tanks.

I removed the original dryer and replaced it with a Bendix AD-9. Since then I have had no water appear at any of the tank drains. When I return to Michigan I plan to install lines and remote valves for draining the tanks. No more crawling under the coach to drain or the cable drain valves that I've used and found that they don't always seal tight on closure.
