Review on VIAIRSuper Duty Onboard Air System by Bryan Orozco

I'm curious about this article. So much work to install it. Unless you anchor it to flat ground. When I first used it, it quickly inflated my 32-inch tires (about 75 seconds per tire). several times later. It takes about twice as long to inflate my tires. Still faster than my little MV-50, but not by much. Definitely not $300 faster. Edit 9/2/14 and used again this weekend for my 285/70/17 tires. From 20psi to 38psi each tire took 4 minutes. I had to stop airing and wait. to catch up. Considering the MV-50 could do it in 5 minutes. That's not a very good air system. Is there something wrong with me? I will contact VIAIR and see what they say. But I'm not impressed with this air system. :(
