Some items are difficult or dangerous to transport, unless you prepare them carefully ahead of time. And you can do serious damage to your appliances if they aren't properly stabilized for travel. Start by draining all fluids -- oil, gas, etc. -- from your power and yard tools so they won't leak.
Dispose of all corrosive and volatile chemicals -- such as oil, antifreeze, paint, and gasoline.
Once you have cleaned out your refrigerator and freezer, leave the doors open to decrease the humidity. And before packing these items on the truck, place a piece of coal or layer of baking soda in the bottom to prevent mildew and musty smells.
You will also want to block your washer machine to prevent damage during the move.
If you plan to transport a piano, have a trained piano mover prepare your piano for travel.
You might also want to seek special advice from your local nursery about transporting any plants, and from your vet about traveling with your pet.
