Hi, John!
The first one built is in the pictures on Andrew's site, and I know of a few currently under construction (and several more that have been, or are being, heavily modified), but I'm not currently aware of anyone, here, documenting their build. I can't call our build a
Campster12 anymore ... it's grown to 14' and has a completely different front end ... I'm calling it the
Kampster14 PHd, but Kay simply calls it the
TugDrop ...

...!
If you build one, be sure to start a build thread and show us how you interpret the idea ...

...! Good Luck, and as always ...
CHEERS!
