On the face of it purely as a photo, the first is more pleasing to the eye, or at least my eye.
Any photo should tell a story in and of itself.
The first draws your eye in more easily with the 'funnel' effect, down through the row, and the direction of the truck at the end points your eye to the building, where you then see the signage.
The second photo, is just that, a picture not a story. that 'misplaced' van breaks up the flow and the eye doesn't follow a pre determined path like the first.

PS. One other thing, and this is totally subjective, what about photo shopping the name onto that right hand front upper corner of the tall white building just for the photos? It'll bring the eye to it more easily, but it may have other ramifications as well, what if people drive in expecting to see it, then they also might think, well if that's photoshopped, how much else has been too, ie number of vehicles etc
