I am looking for a portable air tank abour 7-9 gallons that is vertical NOT horizontal. I've seen them before. As a matter of fact, I bought one from Sam's Club a couple of years ago, it's just in Colorado So, anyone know where I can get one? I willing to order via ebay, internet, telephone, etc. It will just fit better in my enclosed trailer. I am also hoping to find one that will hold >125 psi, although I haven't had much luck finding any that do that. Also, if you have one like I am describing, post up the size, mr, etc, so that maybe I can research that route as well. And as always, thank you again for your support!
