I might be getting a little ahead of myself here but I had to use aluminum on the rear lift gate. It's still in the early stages and haven't figured out how to accomplish the lifting an tilting mechanics of the folding and lifting without hydrolics. I'll probably need to configure a simple pulley and winching system like a cable bucket for a crane.
I wish I had a milling machine so I could run a single rod across then have it pulled up and down for raising and lowering with a single wire in the middle for a winch.
