My pristine 2006 TBSS got rear ended by a 1999 Tahoe (everyone stopped for the fire truck except for him - green means go no matter what to some people, I guess). Driving home the rear cargo area sounded like the tailgate was just not happy. I can't open it, but the tailgate itself doesn't look too damaged - the bottom lip might be bent, but I can't see it because the bumper cover is scrunched up over it. Should I demand a new tailgate besides the other obvious repairs? Am I in for a lifetime of tailgate misery (squeaks, leaks, etc.)?
