New for 1957 was the GRD 304-F-2, a variation on the old high-lift mobile container dumper introduced in 1954. The F2 was basically a GRD attachment fitted to the rear of a commercial truck, which could be used to haul and empty the bottom-hinged Dumpsters either into a transfer trailer, or directly at the landfill. Using a motor truck gave the F-2 greater versatility, allowing it to operate on main roads and interstate highways were the old GRD tractor could not go.

DEMPSTER COMPACTION TRAILER
42 and 53-cubic yard compaction semi-trailers were introduced in 1960, suitable for use at permanent transfer stations, or for mobile operations in conjunction with the GRD 304/304-F-2. The gaping hopper held 16 cubic yards, and the horizontal packer/ejector ram had its own power plant for independent operation.
