Bill, yeah the sand ballasting was kind of a
tongue in cheek suggestion. I was trying to get creative and spur some
discussion on ballasting a large air volume and still make it
trailerable. Also I haven't looked up the density of sand but expect
that it wouldn't compare well to lead or even concrete. :-)
Way
more practical to go with a semi-dry compartment like you
suggested.
