Ford built those in Mexico but not for US import due to EPA & safety regulations. Dodge also built a Ram in similar body configuration in Mexico.
Regarding the few that made it into the USA, such as the LASD and Coast Guard vehicles, it was once possible for government and law enforcement agencies to get waivers of EPA and/or highway safety regs for certain special purpose vehicles on a very limited basis. But, like any good things, those days have been governmented away forever.
