Yeah, that mesh looks tricky. Frame is a good choice. Only other thing I could see would be to perhaps try and hit each joint of the mesh with CA...but I imagine it would snap off after you trim. The frame works...makes sense.
My scene idea is to show the pickup with a flat (via pick axe!) and just a trail of blood leading to an open sewer entrance. The poor bastard didn't even have a chance to finish his Coke.
