Mobile Slaughterhouse (a.k.a. Slaughterhouse on Wheels)
A retrofitted diesel truck that serves as a slaughterhouse for farmers in remote areas of Washington and Oregon without easy access to U.S.D.A. approved butchering facilities. The mobile slaughterhouse is federally sanctioned and comes complete with a 300-gallon water tank, a cooling locker with carcass hooks, and a butcher.
Thanks to Gerard for the heads-up on this bit of jargon.
