Has anybody made this mod? Dealer say's you cannot do it because of computer etc. I don't believe it. Battery out fit I use say's they do them. They use a continuous selonoid and the appropreate wiring and have no problems. Any info appreciated.

    I have a new body 07 silverado, it needs a second HIGH reserve battery. Between the computers (Nav, stereo, alarm, radar detector, bla, bla,bla) the now third battery goes dead if not used in 48 hrs. Dealer says I have no problem, just diss the radar detector. I need a kit that will work like a boat setup, I think??? Any help??
