The same '87 VW camper booklet that states 13.2 gallons:
13.2--10.5   green
10.5--4.0    yellow
4.0--0.8     red
(It leaves unstated that below 0.8 = no LED)

I fill my tank full with good Boulder water (at 5,400') and
head west.  Eisenhower Tunnel is over 11,000' and Vail Pass
over 10,000'.  Then it is downhill to Utah.

Camping alone, that 13.2 gallons lasts easily over a
week.  I conserve by drinking other than water.  ;-)

When I head out I fill my gas tank, too.  Don't you?  That
is more weight....
