Trailmobile factory delivery drivers in 1938 as they stop at the Hilltop Service Station on Rte 22 in Cambridge. Ohio. The Trailmobile factory was in Cincinnati, Ohio and the drivers would stop here for bunkrooms and refueling. The semi tractor appears to be a Chevrolet and the second tractor has had its front wheels removed and it is attached to the fifth wheel of the other. Notice the crude sleeper cab on the truck.
