Unsure if this is just in the muldraugh gas station (farthest one south) or map wide, but I don't recall seeing any urinals while looting.
Edit: Also posters, the citrus posters in the gas station are also invisible
Edit2: Many cosmetic things that goes on a wall is invisible but able to be interacted with (picking up and placing). So far it has been some posters, hanging urinals, air blowers
