Is it the right truck for you?

Side dumps virtually eliminate the raised-body tip-over that kills end-dump operators every year. They cost more up front but pay it back in safety, speed, and access to roadway and pipeline work.

Best for

  • Windrow dumping along roadway shoulders
  • Sloped or unstable ground
  • Sticky material that hangs in an end dump

Skip it if

  • You need to dump into a hopper or confined space
  • Your budget is tight — side dumps cost more than end dumps
