Regarding the E-mail from Harald Rust.    I followed up on his information
on the Sure Power Isolators and at their site
http://www.surepwr.com/index.html    is a lot of very good information that
would be of interest to anyone thinking of adding a second battery.    On
their site under Featured Areas / Electronic Brochures the very last
brochure under miscellaneous is titled "Introduction To Batteries and
Charging Systems" and should be a must read for anyone doing his own setup.
Also under "Needing Help?" the article "Selecting A Battery Isolator" has
the exact setup that Harald described (pg 4 of 4) and is for the Volkswagen
Vanagon.   How about more reading and in some cases less bantering.
Peace!
