I would say LWB F60L's, but I am with Tony that I are most likely cab 12's...but I am not putting any money on it, as there is something strange about the trucks.

Cab 13's have the front part of the fenders fitted to the front clip....so, if the clips are removed, than you can't fit the front part of the fender. But the picture does show full fenders. Or do the trucks in the picture retain the cab13 front clips, and were the sides cut out of them???

What about the GS bodies? Is that a drop shadow under the top edge of the body......or did someone cut holes in the sides? I think Hanno's is right that the bodies have been move forward, but I understand the design of the long wheelwells allowed the bodies to either be fitted with, or without, the spare wheel carrier.

It's certainly a fascinating picture, Hanno!
