Scott spotted this unusual item. If I understand correctly, this has been made to provide a fuel source (out of charcoal) for a jeep engine. I’m not sure what makes this specifically unique for a jeep, as similar systems have been attached to cars. According to this document, a gasifier has been fueling a jeep since 1981 in Laos.
