Hi Eric -

I have a rubberized outdoor carpet that sits flat between the rear cushion
and the hatch. It covers most of the steel area of the rear hatch and seems
to work fairly well at reducing vibration noise and engine compartment
sounds.  I often wonder if it adds any heat increase to the engine
compartment.

The carpet can also be used for laying out in front of the sliding door
when stopped and in the camping set-up.
