I cannot verify this, however I remember seeing somewhere that the factory where the 2/3500's are put together the mega's and the QC LB's bairly make it past a certian turn on the assembly line due to a support beam or some machine.

 

i heard a rumor that in feb that they will have a mega cab willbe avl.but now how true that is ,it came from the dealer but he couldn't verfiy.
