I know you Gov't employees at the Dept of Defense don't exercise common sense. Let's compare this a bit. The plumber doesnt need to go into your dresser. However, a Tech may need to go into the trunk of a vehicle to turn off a certain feature such as a fuel inertia switch, or air ride to service a vehicle. Big difference there.
Have you serviced a Crown Vic? Until you do, then you don't have an opinion to speak. There is a good reason, it is called turning off the air ride suspension as some of them have it. You turn it off via in the trunk, just like some expeditions and Navigators. If you lift the vehicle up in the air with it on, the bags will dinflate and you can cause damage.
Granted the tech put the parts in the trunk to transport them to the service bay and prevented them from tearing the interior. I am sure you would find fault either way, so lets just agree to disagree being you are that bored, you invent stuff to complain about.
