Building a Chevy Mac Daddy dually (rare chevy 6 door dually) my plans are to bag, body and stretch. I want to stretch the bed for a second rear obviously stretching the wheel wells also. A question I have about that is there any way to get the second rear operational gear wise? Or will it just be a dead rear? I know how to do the brakes on it. I also am planning on a full swap to a complete cummins drivetrain for towing reasons. I kno that the year is a complete visual check but the concerns I have is if I am stopped by officers is there realli anything they can do about it all? And the other question is towing wise am I now aloud to tow more weight or do I have to get it re titled? I'm from PA btw. Thanks for any answers and any ideas about the build.
