Milwaukee PACKOUT Large Tool Box

When a job calls for the toughest, most indestructible tool storage you can get your hands on, Milwaukee's PACKOUT Large Tool Box is there to endure whatever is thrown its way.

It boasts an impact-resistant body with metal-reinforced corners — along with a metal-reinforced carry handle and heavy duty latches — that can hold up to 100 lbs of weight. It also has an IP65-rated weather seal to keep out rain and worksite debris.

What makes the PACKOUT series of tool boxes even more awesome is that all the various sizes/styles feature integrated locking cleats, so they can be stacked and securely connected together into one modular rolling tool transport system:

The 22" PACKOUT Large Tool Box (model#: 48-22-8425) is $105 on Amazon and is the component I would personally suggest starting with before you work your way up to the full rolling system.
