"Lets you haul big loads without having to rebuild your pickup," says William Duncan, inventor of a new high-sided sliding box for pickups that fastens easily to the bed of any pickup and rolls out to dump itself when full.

"You can park it on its stand while you fill it -- for instance, while ripping old shingles off a roof. Then, when full, you can back under it with your pickup to haul it away. It's especially good for lightweight, bulky material but hauls as much weight as your pickup can handle," Duncan told FARM SHOW.

The dump box fastens to the pickup bed with two bolt-down, quick-release brackets between the rear box posts and slides on rollers. To dump it, just roll the box out the rear till the load is over center and it dumps itself. A pair of coil springs, fastened to the front of the dump box, pulls it back to its normal travel position when empty.

Standard camper jack stands are supplied to remove the dumper from the pickup. Just fasten them to the four corners of the box and drive out from underneath. No changes are made in the pickup itself, explains Duncan.

The all-steel box, made with 14 ga. material, weighs 800 lbs. Fits any size and make of pickup, with a special bracket needed for Dodge pickups.
