The rear hatch extensions should definitely not be used while the engine
is running or the vehicle moving.  Exhaust gases, and especially CO can
and *will* be drawn into the opening.  I think the ones made and/or sold
by others will make this clear, and the owner's manual mentions this
too.

I've hauled enough extra long lumber and so forth to reinforce this
advice, even with the front windows open (or possibly because of this)
the exhaust coming in the back is considerable.

After seeing the links and pics, I made myself one today in about an
hour.
I used some MSD plastic (like very hard nylon or teflon) stuff I had
around. Also an old seat belt eye-bolt. I think mine may even work while
driving if the exhaust doesn't eddy around and come inside.
 Mine looks a bit like the Go Westy $20+ one, with a flat strut that
hooks
around the post on the body and that seat belt eye bolt sticking up to
catch
the latch on the hatch. I can close the hatch with one hand without
bending
over. I think my dog is going to love me (even more) this summer.
