If you need to haul more per load, or if you need to haul two different loads with the same truck to different destinations without unhooking, the new Walk-Through B-Train Aluminum Live-Floor trailer may have potential. This 62 foot-8 inch, thin-wall-aluminum trailer configuration can be top-loaded, baler loaded or compactor loaded, and with a live floor and a hydraulic system that brings the two trailers together, unloading possibilities are increased.
