One thing I have noticed is that I have been unable to find much advertising in magazines specializing in diesel trucks?? My assumption is that they are having a hard time keeping up with current demand. There is room for tremendous growth in that market. IMO AERO is the clear leader there.
Like all penny stocks there are no guarantees. Most pennies remain low priced pennies. Something always goes wrong in them like dilution, convertibles etc. The majority of penny stocks remain under .10 and much lower. That's the reality. I also hold other penny stocks still waiting on promises to be fulfilled. It's the nature of most penny stocks. Makes for a lot of hopes and dreams. We all live for the possible runs many which never happen.
Love the picture, but you can get +2 MPG just by making sure your tires are properly inflated. The MPG question really does NEED to be answered by an independent party.
