Has anyone seen one of these in the States? It is a 1977 25' Class A Mercedes Benz Motorhome. It has a 4 cyl Diesel Engine with a 4 speed Transmission. Is there any info out there about the engine? (what size?, OHV?, Prechambers?) It looks like a flathead, but I don't think that would be the case. I have done a yahoo search, but nothing on this beast. Any help would be appreciated. Thanks in advance, Rich
