Best air compressor for airing up after 4x4ing

Hey Gang, I found a link that has some good info on compressors but I am still left a bit confused. I like the ARB products $$$ but one of the gang on the Bill Burke 4x4 excursion to Anza had a sexy CO2 tank and swore by it. Now, the CO2 tank is big (like a scuba tank) and weighs a bit, it also has to get filled somewhere with CO2....so help a novice out. Tell me what you have and help me get over my cheap azz Harbor Freight bike tire pump that overheats and stops at 50 psi.

Step 1: establish your budget.

I've got a 100% duty cycle Viair 12v compressor with a 2 1/2 gallon tank mounted on my other truck. It is pretty slow for filling big tires, but it will never run out of air. I want to say that was around $250?

One of my friends runs a York engine driven compressor. He can run an impact gun off of it without a tank, fills up tires fast. He sourced the compressor from the junkyard and made the brackets himself, so he's only into it for ~$100, kits are available for around $500. Oasis makes an electric powered (basically uses a winch motor) York setup that is just as fast (cfm) as the engine driven one, but you can mount it anywhere. Make no mistake about it, they are spendy: The Most Powerful DC Air Compressors in the World

Another friend uses a powertank, it will fill a tire faster than the rest, but like you said, it has to be refilled. I like to borrow it, but I don't like that I can only air up all 4 tires 2 times on a fill. If airing up wuick is your #1 goal, you can even get high flow valve stems and air up in a few seconds!

As much as I'd prefer a substantial air system on the van, I just don't find myself airing down often enough to offset a $800+ system. I think the Viair 440p would be a reasonable compromise for occasional use.

I have no experience with this, but the specs are good and it's budget friendly: Smittybilt - Smittybilt 5.65 CFM Air Compressor - 2781 | 4WheelParts.com

I have the Extreme Air Magnum unit under the floor with a 2 or 3 gallon tank and a few QD's. That thing gives you all the air you need all day.

I am considering the ARB CKMTA12 or a Viair 420C for my new Sprinter SMB. I had Viair on my Tiger. I had no tank on the Tiger and will not on the SMB.

For my occasional use and based on some advice, I got the Viair 88P -- good supposedly for up to 120 psi and 33" tires:

Viair 00088 88P Portable Air Compressor https://www.amazon.com/dp/B005ASY23I..._eLYTybK0MPYSF

Haven't used it yet. May be underpowered for some but small, inexpensive and well reviewed.

I use a 10lb CO2 bottle as my primary source and a 12V Air Zenith compressor with a 3 gallon tank as my backup. The CO2 is a very elegant method as it is very quick. My 10lb setup allows for nearly 20 fills @ 20psi each on a 33" tire. I run 20psi offroad and 35-40 on road. Increasing the fill pressure will decrease the number of tires you can service.

I will be running a York 210 belt driven compressor as soon as I can patch enough time together to make the bracket.
