Our 5-7 yard dump truck is just the right size for hauling rock and decorative bark. With our 5-7 yard capacity, we feel that it's the right size for a lot of residential and small commercial customers who don't quite need the amount of material a full size dump truck will bring. It's a good amount if you just need a fresh look on your driveway, a stock pile for your own maintenance needs, or when spring time rolls around and don't want the hassle of making multiple trips to the bark facility (Not to mention having to clean out your pickup or trailer once you're finished).
