Thanks for sharing the original pic of yours and the plans to it. This definitely makes it so much easier in my garage to move the doors around and protects them. The worst damage to the entire Jeep is the passenger side door when I had it resting against my workbench and it slid down and fell and scratched up the paint. This cart prevents that now.
Also, with the doors right there, I just throw the plastic windows over the top of it and that's where they will stay. It is a multi purpose cart.
Very welcome. I was surprised I hadn't seen more of them here.
You're right too, it's really nice to move out of the way and great for extra storage.
I have thought about making a canvas cover for mine.
If I do it, I'll add a section of wood across the top crossbar, screw some snap bases into the wood. Then have snap bases on the outer crossbar corners. The cover would just snap on/off and give a little protection to the doors from falling objects.
