My quick read was light vehicles are exempt, as are heavy ones. Which leaves a bracket in the middle falling under the bulletin's effect. If the object is to ban Humvees, that would be one way. But .... there is that age old English common law principle of The Common Law, meaning the king cannot make a law against one person.

I'd challenge on another angle too, a heavy surplus truck working on a job site, a remote quarry, or other business is much less likely to be in tip-top repair than a commercially sourced vehicle. There are Ford and Kenworth parts suppliers everywhere in the civilized world - but not Bedford, Oshkosh or REO Studebaker dealers.
