Where is Air Chuck on 2002Gulfstream Scenic Cruiser 8404?

This is BS as you do not need to "tie into the air system" as you do not open up the system to add a T into a line. I actually use one of my tank drains which are located at the front of the coach. By putting a male quick connect fitting on after the valve I can still open the valve and let any water out although I NEVER get any. Put the female quick connect on your air hose and you have plenty of 120 psi for about $15. You can do the same to the line for airing up the coach if it needs to be towed and it may already have the quick connect so buy the appropriate end to go on your air line..

Any recommendations on an air compressor? Has anyone used the Air LIft Heavy duty listed in the Camping World catalog?

You have been sadly ill advised. Most upper end coaches have on from the factory.
It's a very simple add. But if your rather carry extra weight of and air compressor so be it.

Who ever advised you of that has no idea what they are talking about!!! Talk to any old truck driver or diesel mechanic out there to get set straight!

Actually that's only sorta correct...if there is ONE chuck, it's usually up front to ADD air to the system to release the brakes...if there's TWO, one is to air UP the system and the other is to air up other stuff...kinda like an innie and an outie. My innie is up front for the tow truck, the outie is in the bay with the fuel and LP tanks....Dennis

Dennis,
From what I've investigated on my coach, even your statement is only partially correct. By that I mean, I have the fitting w/gauge you see in my earlier post on this thread. That whole setup is the "outie" on mine. On the other side of the front end of the fire wall/Generator access compartment, I have a "Shrader" valve. The only thing that shrader valve will air up is the air supply that's tied to that outlet and gauge. It WILL NOT air up the brake release portion of the system. That's my "innie".

The reason I know this is because, I was replacing the left rear axle hub seal and, in doing so, I had to remove the wheels and tires (obviously) and, the hub, which meant the removal of the brake drum too. Now, knowing that my air system leaks down, and, knowing that I had to order the hub seal and it would take at least a day and a half to get to me, I knew I'd have to periodically air the system up, to keep it from reaching the point that the e-brakes would come on automatically.

So, I tried airing it up through that shrader valve up front. Nope, wasn't happening. But, I knew of another shrader valve, right on the bottom of the air dryer. So, I tried that one, yep, that's the one that's used on my chassis to keep the system supplied to keep the brakes from being automatically applied. And, as such, it's the one used to air the system up so the brakes can be released if they've been manually set.

So, that's kind of why I said your statement is partially correct. No offence.

Fred,

Thanks! I'll show them this on Monday.

Thanks again!

I found a 2002 Gulfstream Scenic Cruiser 8404 for sale with the statement that it is on a Freightliner chassis, so I am assuming a Freightliner chassis.

Freightliner equips all their chassis with an auxiliary air supply manifold. It is actually located by the coach manufacturer.

Look at the link below, go to page 32, and you'll see a picture of what you're looking for.

Mine is in the electric bay below the driver's feet.

I was strongly advised not to tie into the coach's air system as it just causes problems. I've heard that several times now.

My Goof Stream did not have one, but it's easy to install.
On mine there is a T connection at the air horn solenoid on the right hand side above the generator. Just add an air chuck there.
