Mike,

On my 1999 Newell I have 3 air dryers:
one next to the generator (120V auxillary air pump) it has a filter that can be drained,
the second one (12V auxillary air pump) located in the Aqua Hot bay & the drain for it is located in the passenger side drive axle well - it has a petcock to open and drain,
the third one is in the driver's side tag well - it is a spin on filter and it keeps the engine air system dry.

There are also a couple of air bladder tanks that keep the air brake system dry. They are located under the coach between the drive axle and the tag axle (petcocks). There is one more in the front of the coach around the steering axle.

Hope this helps. If it doesn't, do like the rest of us do: call Newell!
