In terms of practicality, I think this is a "from land-to land" design. It' won't work on container ships and double-decked trains can only allow them on the "top bunk", so to speak.

So much for my pea brain! They definitely upped the frontal area.When Fruehauf did their "high-cube" trailer combo in the 1980s,they also increased area.Since the rig was so clean,even with the extra frontal area they still netted less overall drag,better mpg,with extra cargo to boot! Not a bad business plan.Would these clear U.S.A. bridges and overpasses?
