But how does a 60lb bag of clothes fly out of the bed of a pickup truck unless it is ontop of something higher than the tailgate?
I had brand new, king size mattress literally lift up and fly out of the bed of my truck once.
I didn't think it would move an inch and only had one strap on it and wasn't going very far. Don't have a clue how the strap came undone/mattress got out from under the strap, but it was like a kite. Up and gone in 3 seconds.
