okay i was denyed on my first request at a transfer dump because it couldn't work for ror but humor me on this it might work. if the trailer is an indepentant vehicle you must get in it and use f3 and f4 to slide the trailer's box forwards and backwards using hydros. so to load the trailer's box on the truck you must slide the rear box forwards to where it barely hangs over the front of the trailer, then get into the truck and use f3-f4 to send ties from the top of the truck's dump box to the front of the trailer's box. then use O to secure the front ties to the front of the trailer's box. you can then pull the box onto the truck and release the ties then quickly reset them, then the trailer's box is sucessfully loaded into the truck's. so pull away and dump your box then do the process backwards to get the trailer's box sucessfully back onto the trailer.
type of vehicle: kenworth t800h transfer dump
power: 515hp detriot diesel
weight (truck and trailer): about 55,000lbs.
