Lifting stuff up and over my tailgate (>30 lbs) has become a real problem. Age and the sins of my youth are catching up, been told I need both knees and left shoulder replaced. I have seen pics of swinging tailgates and am interested in doing this. My truck is a '66 C10 SWB stepside. Have some ideas how to do this but wanted to check this forum to see if anybody has done this and their process.
