I had always wanted a source of onboard air, however never wanted to pay the prices to have it. So winning a free tank worked out great!
I received my tank and regulator about 3 days after I got Motion Offroad my info. They even put in a personal note about thanking me for joining GLXJ.
In the box was the tank and the regulator. The regulator has 2 gauges on it (one for showing how full it is, and one for showing what psi your running at). I had it filled at my local welding supply shop for about $10. Went and picked up a hose and airchuck for about another $15 and went home and put it all together. I had to try it out, and all I can say is WOW!! Performed great, and went from 10psi to 30psi in about 30 seconds tops. Your not going to find that kind of power in an air-compressor that you can run in your rig. I've also ran an air-gun to change my tires and it powered that without issues as well.
I highly recomend the Motion Offroad C02 tank. Now that I have one, I can't ever see hitting the trails without one. The Motion Offroad tank is probally one of the cheapest on the market, and performs just as well as any high-dollar unit. I wouldn't hesitate to purchase one at the price of $160, as it's money well spent.
