MANY premium brand manufacturers use the same basic alternator with
integrated regulator as the Vanagon. Mercedes, BMW, Volvo, Audi, Saab,
etc..... Hard to accept that these all would use something "truly
pathetic" to only save a buck. I have owned several of these other
vehicle brands and had good battery life and few charging problems just
as with my Vanagons.
