Here is a 1990 version.f I saw this rig in a parking lot I would think "traveler". A little compressor like that isn't that heavy, certainly way lighter than anyone that would walk around on the roof.
The yellow thing looks to be a small portable generator in a cage.It’s probably strapped to the cargo rail. Maybe all the compartments are full.
There is also something in yellow.
that must be the female version.. LOLHere is a 1990 version.

The one in the first picture has a bra on to protect the front so I would agree with others that it is not a typical squatter.
