I have an '84 and the gas gauge is not linear.  I hit 1/2 tank around
100+ miles and fill up around 250 miles with the needle in the red
taking on 12-13 gallons.  I believe the tank has a 16 gallon capacity.

I thought this was an impossible control system to figure out until I
made the connection between top-to-bottom and front-to-back.  The top
lever controls the windshield/defrost vents (right = more, left = less
as depicted by the white triangle above the lever).  The second lever 
controls the temprature (left = fresh air, right = fresh air passed over
the front heater core).  The third lever from the top controls the air
flow at your feet (left = more, right = less).  The last lever controls
fresh (non heated) air flow to the vents above the windows in the back
of the bus (left = more, right = less).

Typical summer setting (no A/C, maximum fresh air flow):

Maximum fresh air, non heated defrost:

Maximum fresh hot air defrost:

Shut it down to run the A/C
