I remember the N's. The 600's and 700's were a pretty good truck with the big 6 or the FT V-8's. The heavy duty models were also good with the Super Duty V-8's. The ND-1000's with the N series Cummins diesels were disasters. You had to remove the cab to do any serious work on them. The engine room was so tight that they had to put a buldge on the hood for the radiator top tank, and the cap stuck right out through the hood. The engine was pretty much in the cab with the driver. The early versions used the same roof as the pickup cab, and was quite cramped. The later versions had a raised roof, which made things a little better. I hate to say it, but truckers in those days didn't think much of Fords at all. Dodge had a better rep., believe it or not. Things got better when the H series cabover (a truck widely known as the 'Two Story Falcon' to give you an idea of how great it was) was replaced by the W series cabover. The W was a serious attempt, not a cobbled together truck like the H and diesel N series was. Same with the L series. It didn't take long to see that Ford had a real heavy duty truck in the Louisville series, and with the W and the L they were able to compete with GMC and International, and blow Dodge out of the big diesel truck business. It was sad to see Ford bail out of the heavy duty truck market just when they built the best big diesel they ever made, the 1997 Aeromax. It looks like they are back to being a joke again......
