some unlikely Spanish combinaciones de vehiculos

[nuyt]

David, the text of the book explicitly names the "camions portacarros" as GMC ACX-504 and White 920. Now, from the above I gather you agree with me taht the GMC above is not of this type. There may have been 504s on strengt after all, since their name does not show up like that in these serious publications. So perhaps they were there as well.
I found at least 3 different tank carriying vehicles in this book:
- the GMC
- a 6x4 White?
- a 4x2 White? see picture below
