Yeah, I'm with Josh, I can't imagine any regionals carrying all the Jepps. You couldn't even get all of them into the cockpit! We use to carry a full set when I flew King Airs and we had to keep them back in the rear cargo area because of the weight and sheer volume of them.
I am glad to have moved on from prop flying though. Now my enroutes and plates all fit into 1 neat binder .
