I don’t have pictures but I used an Isuzu box truck with a 14ft box. I had a 6x5 ft table piano hinged to the wall so it could be raised flat against the wall when not used. Sewing machine at front end of table. Small construction air compressor and lower tool box both against front wall with cabinets over them for supplies. Laptop and printer on top of tool box for invoicing. Truck had side roll door and rear roll door. Generator underneath. Even had air conditioner on top. I was self contained and the truck turned on a dime for small parking lots. I never did it but an awning could have been mounted on the side for shade outside.
I did mobile leather installs for years.
