The idea with the vac was def a good idea... I don't know how easy that would be but def something that should be incorporated in a future product. What if there was like a conveyor belt kinda tool that would fit into the truck bed that could just roll the material off the truck bed and into the spreader...that would be cool. I'm sure its already invented tho. With regards to cost, if you make a product with a big bucket that saves time and money in the long run you can charge me a bunch if I know it will pay itself off. Big buckets make me happy. I'm personally in the market for a good dresser soon myself... But I only want one with a cup holder/ chiller though.
