AERO TANK versus the TRANSFER FLOW Tank. I have been looking at both and see the AERO has a 60gal that is 16 ga Aluminzed steel and doesnt hang down below the frame. Has a lower price in the TDR as oppesed to the web. $568 + Shipping. Uses exixting holes as does the Transfer Flow. Anyone used the Aero Flow? Any opinions which is the better of the two tanks.
