For the past ~5 years, I haven't been able to open my tailgate. I knew what caused it - these 2 & another that was even harder:

I figured I had bent the frame up behind the rear axle, and I thought I could see a small wrinkle in the top flange of each rail where the body mount hole is. But I didn't understand how it could happen with polyurethane body mounts, since they don't compress like the OE vulcanized rubber, and mine didn't look distorted at all. It took a trip to a frame shop to figure out that it was the BODY; not the frame.
