Bogie for heavy duty vehicles

A bogie largely inspired by the one used by dhc6twinotter in his MOC http://www.eurobricks.com/forum/index.php?showtopic=64863&st=0

I was in need for a bogie for an upcoming MOC of mine and found the thread above. To better fit my needs I reduced the wheelbase by 4 L and also (I think) made it at least 1 L thinner. Including the turntable, it is 5 L thick.
