I have a 2004 Monaco dynasty. Have owned it for 9 yrs. and was told the other day that it has an air pump for levelling when parked. Have never heard it as my air takes just about a month to leak down. If it does have one, where would it be. Thanks Henry

On our 2004 Monaco Windsor it is behind the generator and front air tank. Easy to get to, and easy to remove. On ours, the pump corroded, and froze up. I cleaned it up and it worked for a while, but quit again. Like you, our air bags hold pretty well, so when I need to level, I just start the engine and let the main air system fill and level while it’s running. If anyone knows a good source for a replacement, I might replace it.

Most any 12v Viair compressors sold on Amazon will do the job.

The dynasty has it in front of the fuel tank firewall, look behind the rt front tire about 1/3 the way across the coach. I put a viar 450 in mine, had to run a heavier fuse and wire. You have the tightest air system ever!

Wow - a month to leak down. That is very impressive.

The aux air pumps that Monaco used were very quiet, but they are also expensive.

Yours could be running and you don't know that it has. They only usually run for a short time and I think they don't run at night (to keep noise down while sleeping), but I'm not sure about this and how Monaco keeps it from running at night).

A lot of people have gone with the Viar (the 450 is nice because it rated for continuous duty). Probably more compressor than needed for the intermittent tank refresh.

Moving the compressor to an inside bay can extend its life. Be careful about location if noise is a concern.

As Shootist above says - make sure to run a heavy fuse and wire if you upgrade the compressor.

Yes they run at night, that's why I and others installed a switch to be able to turn the aux pump off. It is usually only a problem with a very out of level site combined with cool temps, otherwise mine runs maybe 2 times a day for 30 seconds. Also I moved the unit inside a bay compartment to get it out to the weather and make it easier to access.

I haven’t looked yet but is the fuse for the OE Pump located up under the drivers seat electric bay?

Northwest RV Supply has a listing for the original compressor with plug and play connections. I bought one from them 7 years ago and then moved it inside the bin behind the tag axle. I was outside just ahead of the drive axle in all the slop and road debris. It worked great there and was quiet too. Now they are extremely expensive and have to be ordered. Why Monaco would put it outside in all the weather I don't know....

I found the pump and you are right about it being quiet. I checked it and it works fine. I just didn’t hear it.
Thanks for the help.

I found the fuse and it is good. I’ll look into it further when my back gets better.

My 2005 doesn't have 1, wish it did in cold weather got a pretty good leak

Pretty sure they were Thomas Betts 12v compressor. I think I saw post just the compressor was about $450.
If designing from scratch as some owners found nothing where pump was. I would add an unloader/unloading check valve. Compressor would initially start unloaded.
A compressor pressure controller usually has bleed built in after relay snaps open. Not sure if pressure control switching is on the coach somewhere.

Believe '05 was the only year Monaco 'experimented' with a Firestone leveling system, that didn't use an electric aux compressor

!

HWH on earlier models did, and Valid / Powergear on later models did as well.

I've often wondered why many other coaches have air / pneumatic suspension but hydraulic levelers.

My King Aire has pneumatic levelers for travel and temporary stays but it starts to get wobbly after a week or so.
