no pics but years ago i made one that was full width above the windscreen and extended in the centre, it enabled a speaker above passenger and driver, a shallow 'cubby' above driver and passenger and the centre housed a cb at 90 degrees facing the driver and two angled downlights plus a few switches.
Being full width the internal gutters supported most of the weight
