I picked like 22 pallets of water (shrink wrapped obv) and threw a pull strap strap across the back of them and called it a day. After I started rolling I started second guessing myself if that was enough? The other issue is they put one of the pallets right up on the wall of the trailer so one side of the strap isn't making contact with the pallet/cases of water. Think I'll be good? It's only going like 300 miles.
