Titled as a 1966 'TRUCK' no series or model info, so let's just call it an assumption on my part. Though, I have not pulled block numbers, axle numbers, trans numbers to confirm anything yet due to the massive amount of mud where it sits and the need to do some serious cleaning to remove years of crud blocking the stamped numbers.
First the DD was throwing me off as the only D I could find was Diesel and the engine was clearly not a toroflex. Nor would there be reason for "DD" double diesel. So It had my head spinning as on the 66 VIN listing page there were a few DD prefix VINs, but again I had no reference to the DD meaning.
Otherwise I thought I had figured it out, 4000 series 108" wheelbase but all in all wanted the opinion of other folks who were more familiar with this age of truck. My oldest vehicle before this was a '81 Land Rover. So once again, default to those with more knowledge, which I certainly hope to gain from these forums and the pending wrench-mania that will be my next 3 months. (ambitious much? why yes I am.)
Cheers for taking the time to decode for me.
