I installed a second isolated battery in my truck that charges as I drive. I
wrote an article for Astronomy Technology Today on my setup in the
September/October 2012 issue. I will see if I can post a link to the article.

I would think that carrying a generator around just to power a laptop is gross
overkill. That decision should be made based on actual need...and only the
truly power hungry should need a generator.
While my power needs in the field vary from trip to trip, I have been using a
100W solar panel/30A charge controller for over a year with excellent results.
The "coach" battery in my Westfalia is a 120 AH AGM unit. Both that battery
and my 22 AH Werker AGM (astronomy equipment servant) get tied together for
re-charge. In full sun following a day/night's usage cycle, the charge
controller usually kicks into idle mode by early afternoon.
YMMV,
Darrell
