Hurt my Dart

I hurt my Dart yesterday morning. I had loaded the truck with stuff for a flea market and moved the Dart out of the garage to park the truck overnight. The Dart was parked off to the side by the other door. The rear view mirror was blocked and the side mirrors were tucked in for door clearance. I had pulled straight in ok but it was close. When I was backing out, I heard a 'crunch" and wife frantically waving to stop. (too late). The backkup sensor didn't work right because the tailgate was down. Hurt the left rear quarter panel below the gas cap.
Guess I'll find out Monday who I file a claim with....Haggerty or Allstate. Can I file a claim against myself? Is it hit and run because I left with the truck and didn't call the cops? Guys, I looked at the crunch and almost threw up. Dumb sh#t!!
