Is there no discreet way to move the dead?

So, I'm driving to work this morning. Driving, driving, driving. Look at me drive. And as I'm passing what looks like a tow truck on the highway, I notice it's not really a tow truck at all. Or, it is, it's just not towing a vehicle.

Rigged up to the back of this, uh, truck (?) is a vault. Like, a casket vault. Like, what caskets, which store dead people, are buried in. And it's dirty, as if just plucked from the earth. And I'm willing to bet at least, like, $8 that there was a casket inside.
