I've been wondering about this since reading that other thread. Our 2003 Montana has the parallax and it does a good job of maintaining the battery without modification. We're about to take delivery on a new Montana and this has me concerned. Is it truly fact that the converter in the new ones will overcharge the battery if I don't add this $25 module?
See another Montana or Mountaineer on the road? Flash lights twice, it might be one of us!
