For nearly half a century, the U-Haul box truck has been a fixture of the Tulsa skyline.

In the 1970s, U-Haul was putting trailers on top of buildings throughout the country, as part of its advertising campaign. But in 1978, U-Haul placed an actual truck on the roof of a building in Tulsa and it’s been there ever since. 

According to the Tulsa Foundation for Architecture, this was the first instance of a U-Haul truck being placed on a building, rather than a trailer. https://justacarguy.blogspot.com/2018/05/u-haul-created-out-of-necessity-when.html
