John, for CW, just 20w is enough to work the world.
I worked off of motorcycle batteries for about 18 years.
I worked portable using my motorcycles' battery for about 18 years.
Most of the time I had the Argonaut 509 and 405 amp (50w).
Later I had a Scout, then went to the Argosy (50w).
I never ran more than 20w CW, but for SSB I usually ran the full 50w.
That's OK, because SSB doesn't have as high of duty cycle as CW.
You didn't say if yours is the analog or digital version.
Hopefully the analog version, because if you turn off its dial lamps, it
draws only about 150mA current on RX and you can literally run forever off
of a small battery.
I don't know why but most people always look at battery power under TX.
This is unrealistic.
The battery killer is the RX current. You need to get it as low as can be.
Turn off everything you can, and use headphones. This will give you a few
more hours of operation.

Thanks for the suggestion to use fishing weights to terminate the radials.
It sounds safer as long as you don't chew the weights.
I have an opportunity to make the trip this year. It is turning into a
grand tour as I have family between here and there and so I get to visit
along the way. If I am going to do it, what better excuse to try a little
portable QRP or whatever. The Argosy will go to 50 W but I suspect that
might have an effect on battery life.
