I have the same Wave 3 setup as mentioned by Jim Felder and love it.  There
is a video made by some Canadian dude (can't recall his name) describing
the installation.  If it's really cold (below 40F by my admittedly wimpy
standards) I crack two windows for crossflow and run it at night.  If I
recall correctly, the instructions call for 20 square inches, and I drop
that further if there's a wind.  I also make sure that whoever is sleeping
above has their head towards the rear of the van to make sure that pillows,
stuffed animals, etc, can't fall on the heater.  I have a Riviera with the
straight up pop top, so that is easily done.  If I had a Westy, I would
consider a cargo net to cover the opening while sleeping above.  With a few
precautions, the Wave 3 is safe, affordable  heater that is silent, doesn't
need battery power, and I love the radiant heat.  It really extends the
seasons that the camper can be used with comfort.
