While both trailers have small edit suites, the second control room in the new vehicle can also be used as an edit suite when needed.

Another major upgrade is in the audio wiring. Since the previous trailer was built, IP audio has evolved rapidly. An Axia Audio network handles the audio throughout. The mixer in the main control room is an Allen and Heath GL2800, but each channel and each output is connected to audio network nodes so the full capability of audio routing and switching is still realized. The routing capability also allows the main studio to be accessed by the second control room if needed (and vice versa). Two full programs (and likely more) can be produced within the vehicle.

The high chassis design also helped with wiring. The wire count was reduced by the IP audio network to begin with, but the trailer design allows wiring to be run in the belly of the vehicle, which is much easier for the engineers. Likewise, the golf cart storage is easier; it drives up a ramp instead of being elevated on a platform. The panel on the back that is painted with the Voice of NASCAR is where the golf cart is stored.

With IP at the truck's core, the trailer can connect to the MRN headquarters at any event. A single CAT5 cable to the outside allows the vehicle to access the data servers and the IP phone system from the road.

Additional access is provided by the power and network outlets on the outside of the vehicle. There are also fold-out tables on the exterior to provide more work space.

The new broadcast production vehicle has been designed with all the lessons learned from its predecessors to create a highly efficient use of space with greater connectivity and flexibility in audio routing.
