Something to keep in mind: The empeg is designed to be mounted in a roughly horizontal position (actually tilted 8 degrees with the front end up) for the unit shock absorbers to function properly, so if you can get close to that, you will get longer hard drive life.

Then again, I wouldn't worry to much about it. About a year or so ago, I rigged up an entire computer (with regular hard drives, no shock absorbtion) in my trunk/boot on an DC/AC inverter set to load winamp w/o a display, and I could control the thing with just a numeric keypad. I had it in there for about 6 week, hitting potholes and stuff with no problem.
