Hi Roadhouse -I had something similar where the car was sleeping but it was still drawing power causing the batteries to die, we had to test by taking some fuses off and keeping the truck overnight and see if that helped....in the end we took out the fuse for rear trunk lights and that stopped the draw, the truck has been fine for 2 years now...it was fuse 17 or 18 from the glove box....not saying thats u'r issue but thats another way of looking at it , maybe it might help.
