Dump Trailers 101: Sizes, Capacity and Choosing the Right One

If you haul dirt, gravel, mulch, demolition debris or scrap, a dump trailer can save you hours of hard work. With a push of a button, the hydraulic system lifts the bed and empties the load. Here is how to choose the right dump trailer.

Common Sizes

  • 5×8 and 5×10: Compact trailers for homeowners, landscapers and light jobs.
  • 6×10 and 6×12: A solid middle ground for small contractors.
  • 7×14 and 7×16: Heavy duty trailers for construction, excavation and big hauling jobs.

Weight Capacity (GVWR)

Every trailer has a gross vehicle weight rating, which is the most the trailer and its load can weigh. Materials like gravel and dirt are heavy, so a small trailer can max out fast. Choose a trailer rated for the heaviest material you plan to haul, and make sure your truck can tow it.

Low Profile vs Deckover

Low profile dump trailers sit between the wheels. They are easier to load by hand and have a lower center of gravity for stability. Deckover trailers sit above the wheels, giving you a wider bed for larger equipment.

Hydraulic Lift Types

Smaller trailers often use a single cylinder or scissor lift. Heavier trailers use scissor or telescopic lifts that handle more weight and raise the bed higher for a cleaner dump.

Features to Look For

  • Spreader gate or barn doors on the rear
  • Ramps for loading skid steers and mowers
  • Tarp kit to cover loads on the road
  • Battery charger and wireless remote
  • Galvanized or powder-coated finish to fight rust
  • Electric brakes on all axles

New or Used?

Used dump trailers can be a great value. Check the hydraulics for leaks, test the lift, inspect the floor and frame for cracks and look at the tires and brakes.
