treekiller, the trailer I'm looking it is different, the "bed" itself is onrollers in a track connected to the axles. to lower the bed you have to pull the locking pin on the sideon the trailer, then get in the truck & lock the trailer brakes, while locking the trailer brakes.. back the truck up, this will then slide the "bed" back & down to the ground., you then can drive or winch your car onto the "bed" it will stay up until you get in the truck, pull it forward to put the "bed" back to normal position (still having the trailer brakes locked. hope i explained it well enough to understand
