Moving the holes for the RotoPacks will not effect the mounting of the soft bags - we're only moving them forward about 1/4 inch. Both - 20 is the minimum number for the fabricator to make it cost effective. We do not have a sound understanding of how well these will sell, we are being cautious in our expectations. Asking for the $200 down will help fund the initial build and help us determine demand. As you can see by the pics - its a very complicated piece and the manufacturer costs are high. At the price were asking - we'll just cover the manufacturing costs. Our time spent designing - well let's just say the cost would be over $1,000 to recover that!!!!
