Tarp Trick Dump Truck

We dont have a dump truck so I came up with a trick so we can dump things. Lay a tarp out
fold it over
lay a chain or a tow cable across the middle
fold that over with the ends of the wire hanging out
place in the back of the truck with the wires hanging out the back
when the back is filled with wood chips or debris, place the ends of the chain on a cart or skid steer and drag out the tarp. Its probably common sense...whatever...wanna fight about it?
