OK, just got my truck back. The dealership said that a connecter had come loose, causing the battery to die. The charged it up, check all connecters for corrosion, etc.., and I just drove it home, no issues.
I don't really believe it was a loose connector, but I'll go with it. Got it back, and it seems to be fine.
Oh, and thanks to those who thought they should tell me how I should (or shouldn't!) tint MY windshield!
Seriously though, thanks for all the great input.
One last thing, I asked the service writer about the orange pull cord not working - he said that if the battery is completely dead, it won't work. Don't bite my head off - I'm just telling you what he told me!!!! Makes no sense to me that it would not work when you need it the most.
