Where to Buy

When Doepker introduced our "patent pending" Impact gravel end dump design in 2009, it was the first time our market had seen anything like it.  Strongest, lightest, most stable, multi-purposed, and highest resale in its class is what you receive when you invest in our Impact gravel trailer.  Available in a tridem or tandem, this highly engineered design offers Hardox as the standard tub material integrated with our special tapered tub design that offers superior clean out.  The Impact end dump gravel trailer gives you the ability to move your tub back and forth on the frame to adjust rear tub overhang.  This gives you the flexibility to haul asphalt into a paver or allows you to increase wheelbase to provide the ultimate payload on all of your axle groups when stock piling aggregates or hauling contaminiated soil.  Visit your local dealer to view and discuss all of the great and numerous Doepker advantages and options on this industry changing gravel trailer.
