You're right paul. It's always been a pain figuring out where to air up, and go slow until I find a gas station.. I found this really cool YouTube video on a build it yourself CO2 tank, and just ordered all the parts to put it together. Looks like a nice set up!

Been using CO2 for over 10 years after I gave up on the Powertank due to multiple regulator failures and long delays for recertification (hydro test).
Pretty good video. I went a slightly different way. 20# tank from any weld supply place. They will swap you for a certified full tank for around $25. The 20# is pretty big. I usually fill my tank twice a year - spring and fall. I mount mine on the rear roll cage with a Weld shop bracket modified accordingly for my application. Weld shops do not deal with other tank sizes, but will fill your small one if it is within cert date.
Operation I have 35x12.5x15 tires and none of the others I wheel with are as fast as my CO2 setup. I am slightly faster than the York guys. The 4th tire fills about 1/3 as fast as the first one due to regulator icing. 12 psi to 28 these days. All regulators will ice some less than others. something to think about if you have to more than 4 tires. Takes a while to thaw the reg.
I currently use a goodyear hose the correct length to reach all 4 tires and leave my plastic coil one on the shelf in the garage. I don't like the kinking of the coil hose and I just find the so called rubber hose easier to deal with.
