Need Help with Cable Tray Display

[sbrennan85]

I've spend hours of searching the web for someone with an explanation of how to display cable tray the way I want it shown.  I'm using AutoCAD MEP 2011 and in an isometric view in model space, my cable tray is displaying as what looks like extruded rectangles.

I've messed around with the Display Manager, trying to use Cable Tray Model representation under both MEP Design & Electrical Configurations.

I'm ultimately looking for a view which displays the ladder and rungs for cable tray.  Is this even possible with the default catalog in AutoCAD MEP 2011?

I've attached the file for reference if it helps.
