It looks like two photos where someone has used Photoshop on them. The first two pix have the same exact spot defects in the lower left corner. The last two appear to be the same image with only the artwork different.
In addition, the trucks appear to be the soft sided version with canvas sides from the tension latches along the bottom. There is no way canvas would ever be that smooth. In addition, the rear barn style doors are missing the four vertical locking rods and handles. The fittings they twist into are still on the truck. There is nothing there to hold the doors shut.
At first a very nice Photoshop attempt, but with a closer look, not so good a job. If these were a mockup to get a company to advertise on the trucks, then they are OK.
Remember, if you see it on the internet, It must be true!!!!!!
