Abstract
Abstract A demountable truck body of the ''''roll-on/roll-off'''' type constructed with a false bottom forming a sump for trapping liquid drained from the material loaded in the body and a load material compaction unit associated with the truck body. The compaction unit includes a compacting plate which serves the dual purpose of (1) a compacting element for the compaction unit to compact material into the truck body while it is ''''set-off'''' and (2) a door for the charging opening of the truck body after it is filled. The compacting plate is adapted to be alternately removably attached to the compaction unit and to the truck body over the charging opening.
