I think you'll find the towball removal law was because the Ball obscured the number plate on most passenger cars,
I doubt you'd get pinged in a Patrol as the number plate is on the door.
Light bars are ok now seems to ppl in power caught up with reallity.
Not sure on those pipe rack extensions some ,plumbers, concreters and carpet ppl use.
I had one on my other 4x4 worked a treat bur never left in on
