How about simply hard piping a manifold which would enable you to bypass
the spare tank if you didn't need it.  

The sequence would be:
Main tank
one leg of tee - shutoff valve, spare tank, shutoff valve into a 2nd Tee
2nd leg of tee - shutoff valve, into 2nd tee (after spare tank)
from 2nd tee to regulator
