That's exactly my thoughts as well. On top of that I've cut into more
than one commercially built "air tank" and been surprised and
concerned on how thin they are. A fact that can be confirmed by just
weighing a similar sized air tank compared to a empty propane tank. My
commercially made and sold 10 gallon tire inflator tank doesn't weigh
as much as even my newest small propane tank (and older tanks are
often much heavier). On top of that my portable air tank doesn't have
any way of draining moisture either so why the concern about propane
tanks in this application. Now as a compressor tank something needs to
be done but as has been stated many times in the past mounting it
upside down with appropriate drain fittings attached will cure that
problem (though it might make for slightly wetter air coming out than
a normal tank).
My 30# tank is mounted upside down with angle iron frames for base and
compressor. Plumbing is 3/4" nipple & tee with side inlet from another
tee, up is check valve, down is drain. Down on the first tee is
plugged with feed through outlet from the mid point of the tank space
to avoid any contaminants that may have settled in the bottom area.
