Single axle dolly

Mods please feel free to move this thread if it's not in the correct spot.
I'm wondering if anyone has an idea on how to build a single axle dolly to pull a second trailer?

Something like that is what I'm after, curious about what to use for suspension and what you guys think I should do to secure the hitch to the first trailer..

Use the search section on the forum, there is a build thread from years ago on here for a dolly.
