I was talking with an older gentleman the other day and he told me as we were discussing my '74 F350 that he used to own an older '70s something Ford duallie pickup truck. He said it had an actual pickup bed on it with dual wheels. I was born in '77 so I came on the scene a little late and I don't know everything. I also don't believe everthing everybody tells me. However, this monster kind of perked and interest in me so I thought I'd share the story and see if anybody has experienced any sightings of these such creatures. Next time I cross paths with the man I'll ask about a photo or something.
The 74 f-350 could be bought with a 8' bed single wheel. These trucks have a different wheel base than a normal f150 or f250 long bed. Also on the pass side there is an access panel between the wheel and the cab much larger than the normal tool box. This is where the spare tire went. I'll look for a picture of one.
