First thing he did with those L10's was rip out the lavs and strap a camping toilet in the back of the cockpit.
(So I heard....)
Yes, that is precisely what was done.
However, the L10's that had been converted to freighters that Kalitta purchased, were ex-BA machines, and originally did
not have the usual forward lavs arrangement as other L10 models.
The BA lavs were modular units, directly in line with the R1 door, and these were required to be removed for the installation of the forward cargo bulkhead.
So, Kalitta really had no choice, although having said this, the port-a-potty that was selected was not especially the best available...
