After a year of development, Saskatchewan’s Doepker Industries has introduced a "highly engineered", patent-pending gravel trailer. It’s claimed to be the lightest and strongest such trailer on the market with a tub made of 5/32-in. abrasion-resistant Hardox 450 plate that’s said to provide significant strength combined with an extremely light tare weight. That promises maximum payload and long road life.

They key to its two-in-one design is the adjustable box that moves back and forth in 3-in. increments on the frame to accommodate all types of hauling and in all types of environments.  For instance, moving the tub back over the rear suspension allows the trailer to be switched from asphalt paving use to hauling contaminated soil or just gravel. This normally requires two different trailers.

With the new Impact, the user can remove 12 bolts and position the tub where they need it to be in relation to the suspension, then re-tighten those 12 bolts and go to work.

Other features include a tapered tub "that ensures exceptional cleanout," a design that ensures the trailer is stable when unloading, and high-quality standard components.
