All this talk of using the 12v on the van got me thinking about how
to do it? I've seen criticism but no DIY suggestions.

I have no doubt that in the archives are detailed instructions on
what to do if you want to put a second battery in your VW (not
necessarily a Westie).
With luck they would start at the basics like where do you put the
2nd battery?
What type of switch do you need to put in to isolate the 2nd battery
when the engine is turned off & where do you put that switch?
What size wire should you run to the extra 12v outlets?
Are each of these 'new' outlets fused? Is there a best central place
to put the fuses?

I know that someone has already done the engineering on this, made
the errors, found out what works best & found the best ($$) place to
purchase what's needed. Is there a web site out there with this? Is
there a message # to look for in the archives? Is there a group that
has all this in their FAQ?

Can anyone help?
