Could I achieve this voltage if I add a second storage battery OR is
there a circuit that would allow the single 12 volt battery to step up to
the 17.4 volts?  Same question on the 19 volt computer.

Turns out the SONY is only 7.5 volts so the Radio Shack system should
convert.

It is definitely 12 volt so should go straight through

All in all this is very promising.  I would hope to build a
"station" where all these items can be centralized to get their
power.  Any suggestions on where it would best be wired into the
coach would be appreciated.
