I think I need to clarify a few things, this is not a business I am starting nor is it at a monetary gain for me, it is existing components that the company I work for already sells. The only reason I even mentioned this as a kit is due to it seems that many would be interested in having only rear air suspension. I am not stating nor implying that this kit is superior or worse than the kit Tony sells, I have no experience with the TBSS bags, but simply seeing if you guys would want this as an option.
To recap the only reason I am doing this is for you guys and that is why I am trying to keep the cost as low as I can.
