Air tanks
Just wondering... I was thinking of getting an airtank (compressor like a 150psi max 100% duty) and an tank... the tanks I see look pretty thin, and it would probably be mounted under my vehicle, (I don't know where you all mount yours)
Anyways... I was looking at getting a "Bailout Bottle" or little dive tanks because it is Thick, and used of getting bounced off rocks... however most of these can reach 3000psi....
Not that my pump would go that high, but is this a bad idea (not to mention the costs of the fittings to adapt it, and costs of the tank itself...)
Just want to know opinions....

IMO those thin tanks will be OK. I picked one up, but I need to swap out the bungs to 1/4NPT from 1/8NPT. I plan to mount mine along side my frame rail, and these will protect it for 90% of the hits. A dive bottle may be overkill but hey, I like overkill. Don't get to big of a tank, or it may get banged up a bunch.
Now that you bring it up. The bigger air storage you can get the better. well, buy a big tank, mount it under your truck, put a few trail dents in it till it no longer hits. The you have max air, max GC and only people under your rig see the dents. Ha Ha Ha
I was looking at a low-rider mag at work the other day. I see they sell many sizes of air tanks, and they look to be about 30% cheaper than the 4X4 tanks of the same volume. May be worth a check. Maybe they are thinner and would dent to easy, anyone know?

Huh, huh-huh, huh. You said "bung."
I've been thinking about going the route of Corey and using a CO2 vessel in the back- no worries about compressors overheating or overloading your electrical system. I'm getting tired of spending an hour at the trailhead with my coleman air compressor, thats for sure.. I bet the CO2 is probably at a much higher pressure than your air compressor could ever get and fills tires much faster.

I have a PowerTank as well, but there is always that question lingering in the back of my mind as to when the tank will go dry. Because of this, I am planning on getting a tank and compressor as well. CO2 for tools and seating beads, and the compressor for the airing up.

CO2 is fast. Set the regulator to 150psi and it takes less than 30 seconds to air from 15psi-40 psi per tire. And you can reseat a popped bead too. And run air tools for over 20 minutes straight! I just want to sell my 10lb tank and get a 15lb tank or have 2 10lb tanks to be sure I don't run out.

I have the tank mounted in my truck bed to the side of my truck bed box (I have a chest type~I like the deeper storage) and I got the Powertank at Central4WD. It lasts for a while. There is like over 900 psi in it, though the tank is actually rated for 3500psi. It costs $12.00 to fill it at any welding or fire extinguisher shop that fills on premises. Central Welding Supply is where I get mine filled here in WA. They have stores all over the place, though I usually go to the one off hwy 99 in Lynnwood. CO2 is best because it is simple, cost-effective and the pressure remains constant for the whole volume of the tank. I think Corey said that he last filled his like 2 years ago! I think that my tank has enough air to inflate 39 31" tires from 15-30 psi. That is a lot of gas! I recall the 10lb tank holds 600 gallons of CO2 vapor.

The tanks are the like $159 for a 10lb. and $199? for the 15lb tank. The regulators are like $99 for the Powershot (150 psi non-adjustable~can't use on air tools) and $199 for the adjustable one-I have this one. There are cheaper ones out there. Or you can make your own setup. You can get regulators at the welding shop as well as tanks.

Here is one of the alternatives to the (Power Tank) Powershot:

I built my owm out of a 20Lb CO2 cylinder, a regulator from Williams Baloon and Helium (800-235-4112), I got a style 150 male (the 150's use an o-ring to seal the bottle end) with a 120lb spring, this puts the pressure at the end if the air hose at about 100-110 psi. You can get a higher spring which would air up the tires faster but if you use it on air tools it could damage them. I got one of the coiled yellow Plastic like air hoses from my local hardware store and the fittings to plumb it all together. Total cost approx $115.00 ,not quite as fancy as the power tank but does the same for less money. HTH
