Does anyone have a co2 tank setup? Like power tank, or even better, a homemade version? If so were did you mount it?

I am also interested in this.. i was wondering if i could use the smaller tanks (the ones that persons with breathing difficulties use) and place it in one of the storage compartments.
I have a dumb question... Why?

you can fill tires in about a 1/10 of the time and run air tools off of them if you chose.
Doh!!! I knew that 
I'm just not thinking real straight this morning.

What about those other onboard-air systems with built in compressors, what is the price differance? I have been thinking about this for a while now, I think the passenger side compartment is the best place.

Compressors & tanks take up a lot of room, and need power to run, have to be installed and of course $$. I have a 5# tank at the studio I use for ice carving, I will see if it fits in side storage comp. According to www.powertank.com website, there #10 tank "airs up" 39 tires, so I would think we could get 15-20 "air ups" out of a #5 tank plus the ability to run some air tools. The question is can we find a regulator in the 100-150 psi range, hoses fittings etc?

Welding supply houses deal with CO2 all the time. they'll have regulators and fittings for the CO2 side of things.
Make sure you ask for a regulator. Most welders use a flowgauge or a regulator/flowmeter, you don't want one of those.

wouldn't CO2 on board present a health risk (if it leaks). Why not carry compressed air bottle.
CO2 Carbon Dioxide would only present a health risk if it suddenly and violently lost pressure AND was not tethered or restrained and bottle got flying around(depending on size ) We exhale CO2 so in a mostly CO2 atomsphere we would have breathing difficulties,but open the window...LOL
Most likely bottle would freeze up in cold weather when you needed it most.
I would recomend a compressed air sit-up if you live in a cold weather
locale.
Just remember if you do get a CO2 sit-up,to mount securely ,and have bottle available to be inspected by filling station,(in paint-ball we had to have ours inspected every 2 years)
I also would not install in cab of Avy,at least have some metal/Mid-gate between you and bottle in case of accident.
I`m thinking of just getting a small pancake compresser and tieing that into a voltage inverter and installing in bed for when /If I need it

Compressed air tank is entirely inadequate for filling tires. You would need a huge tank to even fill all four tires. Lots of people use CO2 tanks even in cold climate - the capacity is dramatically higher than compressed air.
Most 'pancake' air compressors will not run significant air tools.
An inverter big enough to run a decent sized compressor costs more than a portable generator that will do more.
If you really need 'on-board air' then a converted A/C compressor (usually a York which does not require oil in the air) driven off your fan-belt works well for tire filling and air tools. I don't know if anyone makes a bracket to fit the AV. try www.onboardair.com

I have a small air compressor that fits in the side storage bin. If I tried to fill all 4 tires after off roading, I better plan on it taking the better part of a couple hours (that including time for it to cool between tires).
A couple guys I know who go wheeling out here have had the tubes in their bumpers sealed and use them as tanks. If you have tube side steps it might be an option, too.

If they are tubeless, get some dry ice, toss a chunk into the tire if you can hold the bead. It'll sublimate into the gas and pressure up the tire...
Since you would store it in a non-sealing insulated container, you can store ice cream or frozen treats with it. Then you could enjoy those while you wait for the tire to explode...
Put in a nitrus system, use the nitrus tank for both - The tires and the boost! (Kinda pricey though..)
Maybe an air-bag system - dual use of the compressor..
..Oh well, back to your idea; `looks good as it is.

I just purchased a 4 lb tank and it fits perfect in the cargo box. I moved the tire iron and placed the bottle behind the mesh compartment.. it holds the bottle great..
it is curently filled with co2 but once i empty it I am going to fill it with nitrogen (gas opposed to a liquid) I have been told that the co2 doesn't last as long and it will end up placing some moisture in the tire (or whatever I use it for) for instance in racing for the air shifters the co2 clogs it becuase of the moisture and i believe that air lockers have had the same issue.
If you do decide to get nitorgen be sure to purchase a bottle and regulator that can handle the pressure..
Once i have completed everything i will follow up with some pics.. (not done... so no pics yet )

)The PowerTank set-up is the best out there. Steve Sazaki has spent a lot of time developing the regulator and the system. I have used PowerTank for many years. Filling 44" tires present no problems. 35's are a breeze. I have used it to run impact tools and even a drill. I have 2 10-lb. bottles. Give Steve a call and tell him KC sent you.

`Doubt it.. CO2 sublemates, there is no liquid state between the solid and gas. It's really just dry ice in a powdered form inside that bottle. Whether it's 90? or 30? below, it'll act close to the same. If you release the gas, of course it'll freeze on the outside where there's moisture. (It can chill to -109?F!) Hopefully no moisture is inside the tank when it's pumped (as in a regular compressed air tank where you have to depend on a trap).

I just put together one of these homemade system and it works fine.
10# C02 Tank with fill up for $125 from Praxair (local welding supply store) - Tanks can be purchased as low as $85 but you need to pay for shipping (weight 15lbs) + a fill (normal cost around $10 - $15)
Regulator from Williams Balloon - Ask for a club discount @ $35 delivered. Get the female version if you want to attach a hose without any adaptors. Otherwise get the male fitting for quick release adaptors. You need to specify the spring pressure. I would suggest the 120 psi spring if you plan to use air tools. If you don't plan to use tools, go with a higher psi for faster inflation.
Inflation hose & air chuck under $15 total. Get a 3/8" hose for the best results.
I use tie downs to secure it.
Total cost under $200 - nothing fancy, it works and fills far faster than any electric compressor and it really beats limping on under inflated tires before finding a gas station.
The BIG advantage of this system is for those who air down large tires for offroading. Going from 15-40 psi on 33-35" tires can take f-o-r-e-v-e-r with even the most powerful electric. C02 will get you from limp to full size faster than Viagra.
I use to hate airing down because it took so long to air back up.. now it is no problem and the improvement with lower air pressure is amazing!! It gives you a lot more traction, makes for a softer ride, and it really reduce the beating the truck gets while offroad.
BTW - I believe the CO2 is stored in a liquid state (not powder) at a constant 800 psi. That is why a fancy model with a pressue guage is useless. You have to weigh the bottle to determine how much "gas" is left inside. 25# full 15# empty on a 10# bottle.
