Hi Dave
The only "Carrier Trailers" i`ve seen here are the Crane 7 and a 1/2 ton recovery trailers (the same as towed by the Chevy above)
New Zealand also had there own conversion to the GMC CCW353
6x4 for use as a carrier transporter there are some club members with GMC`s fitted with decks from these they look standard until you look at the floor of the deck and you can see where all the holes have been filled
