This is a former AAA tow truck.

“1955 Former AAA Tow Truck. 4.2 Jeep engine. Can get to 70 for passing on freeway. Better to stay at 60-65. Runs, drives, fully registered. Ran it to Las Vegas and back. I’m working on replacing the rear main seal and starter. Replace different parts around the truck. Rewired the whole truck. Have other parts. Will look at offers.”
Reminds me of the Tipple Motors (Ferndale, Ca) tow truck that ended up at Willys America.
