 Joe -
 
 We installed the Aerox, 4 place system with a rather large tank in our
 unpressurized ES. We have not flown yet, but so far the equipment is good
 quality and above all, the tech support from the company has been great.
 Great folks! The tank is installed in the left side of the baggage
 compartment below a floor we built for the compartment. The filler is on the
forward wall of the baggage bulkhead - again, below the floor. You can  see
some pictures at:

 Hope this helps.
