I think I solved my own problem! The measurement of the change in water
column height should NOT be the distance one side rises when pressure is
applied, but that distance PLUS the distance the other side falls - i.e.
"the height difference of the ends of the water" as Mark said in his
original e-mail - and I managed to misinterpret! So my 5 inch increase on
one side of the "u" actually would translate into 10 inches difference
between the levels on both sides - which is pretty close to the 11 inch
spec. according to my "enlightened" thinking.

While on the subject, though... The other day, Adam Grove mentioned in his
description of his '91 Westy Syncro for sale (maybe) that the PO had
installed two propane tanks which filled from a common filler valve. I
wonder how this was done? Perhaps just using a "T" and a few elbows and
piping to connect the tanks? I would imagine pipe that was suitable for tank
pressure would be rigid (copper wouldn't be the thing to use, right?) , so I
wonder what effect body flex might have on the system and how the PO took
this into account. Does Adam or anyone else have any input on this??
