it all depends, if the people who had it as a truck and used as a truck BEFORE doodle buging it they probably have a title. If they sold it as a doodle bug or lost the title it probably doesn't as it was never intended to be on the road.
Seen multi-dozens of them in the forties & fifties and never-ever a mention of "TITLES"! Was brought up in the northern tip of NYS and the doodle-bug was the norm for raking and drawing off loose hay to the mows. I had a 46 Studebaker with the biggest rear tires you could imagine and if ya lived another fifty years you couldn't wore it out. GOT THE THING AS A WRECK THAT WASN'T FIT FOR THE ROAD AND IT NEVER FAILED.
