It falls on the frame under the seat and therefore rattles a bit. For $150, it should be sealed with a seal and have a better "lock" that's just a deadbolt. The contents should stay dry as they fit under the seat, especially if your mule has a roof. However, I am sure dust will get into the box as it is not sealed well.
