I have a '74 VW Thing that we tow behind our GMC. I have a semi-tractor air
brake tank in the front 'trunk.' I'd say it's just a little larger than the
5 pound CO2 tank Chuck describes.
This has a schrader valve fitting with a cheap Sears 12 volt air compressor
connected.
I have a regular old household style square D 20-40 water pump pressure
switch that powers up a cig lighter socket under the hood.
The air tank is also connected to a 12 volt solenoid that feeds two very
large air horns mounted on the left front fender.
We use this if the traffic gets heavy, or for other entertainment purposes.
The what-the-SHOOT-WAS-THAT! factor is very high. It is very effective, to
say the least.
We also use it as a "sign" car in parades. Very effective attention getter.
Just another thought... you could justify this so easily --- two birds with
one stone -- you really need that spare 12 volt air compressor if your air
suspension system compressor goes out... so you're only true expense is the
salvage air tank and the big-ole air-horns... Is this classic GMC thinking
or what?? Eh?

| I run my air horns with a five five pound CO2 Tank (like a fire

| is about $5.00. The tank had to be re-certified and stamped just like
| an extinguisher but that was ok too! Cost for this was $15.00 .
| I refill the tank prior to a trip. I don't use the thing unless I
| really need to or I am giving somebody a good by, a hello or????
|
| Normal use requires refilling about once a quarter. I must admit it
| does get the attention of people who normally would not care one way or
| the other.
|
| I always wanted to add a compressor for it and a tank like the big rigs
| do so I would have compressed air to do tires or what ever but never
| found the right set up that would fit anywhere on the GMC. The CO2 tank
| is located in front on the driver side next to the steering and is
| easily removed. When I am not driving I turn it off just like I do my
| front battery. Just a habit! Not a requirent! Chuck in Lompoc, CA
