Cheap trucks anyone?

I read this in the Transport & Logistics News recently.

US Trucking Firms Downsizing
More than 130,000 large trucks are currently parked up in the US equivalent to 7% of the nation’s entire heavy trucking fleet as demand for freight services dwindles. This figure is expected to keep rising as the recession bites. The downside is expected to continue even when the recovery starts. Freight rates are picked to jump as rebounding demand outstrips the industry’s ability to re-commission capacity.

I wonder how that compares to NZ as a percentage, rather than 130,0000?
