Gets expensive and more complex as you get away from the current design standard quickly doesn't it. You can't get the trailer too low in the middle of the span either or it may have clearance issues with steep grade transitions.
How often have folks seen the single wheel setups in the states as oppposed to the double wheels on the trucks (the truck has 6 wheels instead of 10). I've seen a few new trucks set up that way. Its supposed to be more fuel efficient. Probably cost prohibitive to convert an older vehicle. I haven't seen any with the crosswind baffles in between the cab and trailer yet. I've seen several with a plastic shape on the trailer bottom that looks like a ramp. I assume its for aero? Wonder how much improvement that gleens.
