I made this trailer from aluminum crutches and wheels from a walker. My friend made me an trailer hitch and I attached it with 2 screws with knobs from an old futon. It works great and I can carry alot of stuff and go shopping. I also use it to carry my dog around. I attach his crate to it and tie it down with a bungy cord and we are sit to gooooooo...lol Oh forgot to mention it is also adjustable. You can make it wider and longer..lol
