blue box copies

[cortezfenn]

Last fall I bought my 1981 35FCRB that did not come with a "blue box".
I called BB about buying a copy of all the drawings. The reply was that
they don't have them for an 81, but have a set for an 83. I'm hesitant
to be looking at schematics for an 83 that may be different. Any
thoughts? Would anyone be interested in copying and selling me the 81
drawings? A quick question. Is the Sporlan valve a brand name or is it
a type? My summer/winter switch has been bypassed with two manual gate
valves in line under the drivers seat area. Also the water fill valve
from the outside doesn't work. To fill with fresh water, I manually
open some valves under the driver bed to fill the tanks. That original
valve is in the w/h closet. Seem to have several of these solenoid type
water valves that need to be replaced. Trying to get educated. Jim in
