Pickup driver caught after cops find him hauling 53? trailer

Looking at the article linked, the person had an air tank rigged to release the parking brake but there isn't a hose to the connection that would apply the service brake. So the only braking would be done by the truck which is not legal for the size of the trailer.

There is no confirmation either way.
The cop had no mechanical knowledge to determinate how it worked and the journalist knows even less.
So if the trailer brakes work- the only issue is steering and since trailer is on dolly, there is not much forces required.
I would compare this setup to Australian "Road trains" where a truck pulls dozen of trailers. All legal in AU.
Why this topic is 5th wheels? :S
On other hand, that tank looks like fluid tank, not air tank to me?
