This July 08, 1947, article from the Sullivan Daily Times announced the upcoming arrival of the Jeep Caravan to the town of Sullivan, Indiana. It was one of four Jeep Caravans traveling the United State at the time.

The caravan consisted of eight jeeps. One was the CJ-2A fire jeep. Four other CJ-2As sported attachments, including an arc welder, a generator, a compressor, and a line of hydraulic lift implements. Based on the pic below, it looks like 2 wagons and a truck, brand new to the line-up in the summer of 1947, rounded out the caravan.

This July 09, 1947, article from the Sullivan Daily Times announcement was published the next day and featured the CJ-2A fire jeep.
