Larry,
Quick answers:
1. Most anywhere that carries truck parts and supplies will have them or can easily get them. Haldex offers two different types, so know which one you need. A knowledgable parts guy will be able to help.
2. If you have the tools and are fairly strong it's not too bad. As they say, "It ain't rocket science".

I purchased mine online from NAPA and picked it up at my local store.

Not much can go wrong with them. Filters can be changed. Heater can be replaced.
Air Plunger can be replaced.
Still using the 14 year old OEM on my MH.

Larry, what kind of problems are you having??? I have a 99 Alpine, the former owner put a drain valve on the air system located in the far rear compartment. I am a retired trucker, accustomed to dealing with air systems, If the filter is full, it will not absorb any more moisture. You can determin this by draining your air system, if it spits out more than just a very breif spray, you may need to replace the filter. If you can access the dryer, its no big deal to replace the filter and or purge valve. When the compressor reaches its max air pressure, the purge valve will spit, and the compressor will shut down. An air governor regulates the compressor cycles. On an 04 model, unless you have alot of miles, your filter should be ok. On my trucks, they were usually good for 300,000 miles or more, dependding on weather conditions. Hope this helps, old trucker

A year or so ago, I tried [repeat] tried to order a new dryer filter from a sales tech at Bendix [think the 03s have a bendix filter]. Anyway, the tech asked me what symptoms I was having [eg, excessive water or oil in the daily air drain]. I told him neither so he said he would sell me one if I wanted but it didnt sound like I needed it. Sometimes you have to resist temptation to "fix" something and leave well enough alone--a lesson I relearn almost everyday.
