I've had a '78 K10, '77 K20 and my dad's '79 K15 and all 3 have dual 16 gallon tanks.

Wonder what percentage had 20 gallon tanks in them.

I'm pretty sure that the 74c20 is 20. I know the, 76k10/82k25/86c10 are 20 gals.

Not sure if it was optioned with it, but my 74 k10 has dual 20's (one was definitely added later). May have been due to it being optioned for the factory skid plates.
