Parked in the driveway Friday evening and Monday it won't start. Second time in two weeks. Two new batteries were installed at the dealer and mechanic said alternator was good and strong two weeks ago. Now it has lights so I think the batteries are good but it will just click. I called the 800 # and it will be going back to the hospital. I need to depend on this truck but we are not getting off to a good start.
