I just finished a fun little project, a laptop charger integrated
into the cabin of my '84 camper.  Details and photos here:

I'm available to help Vanagon folks with little electrical projects
like this in the San Francisco Bay Area/Santa Cruz, when I'm not
traveling. Tell me your ideas for making your Vanagon a more
convenient place to live or camp!
