Apparently someone has cloned that Beetle 5th-wheel from the 1960s.
That trailer axle looks undersized to me.
I found it on Just A Car Guy. A few days ago he had posted a [mid-engine] bobber/5th-wheel combination that is more aerodynamic.

This —Beetle-sized— with optional clip-on fold-down bunks to make it a tent trailer on demand a fold-out rear porch/ramp and a Basecamp-like toy hauler interior.
