The base element on panel design is to separate what stuff and wires stay in the plane, and what comes out when you pull the panel.
Below is a photo of my panel test fit on the new RV-8 project (third project with this approach). This will be a full dual SkyView EFIS install (a 10” and a 7”), Dynon radio, XPDR and ARINC module mounted on the bulkhead forward of the panel.
On the removable part of the panel there are breakers only for the removable panel stuff; two for the GTN-650, one for the audio panel and one spare. These breaker get power via a 0.093” pin Molex connector from the Left Vital bus. All the interconnection wiring between the GTN and the audio panel comes out with the panel (as do both trays). The connections to all the other stuff are either coax or D connectors. All of the other panel is connected via D connectors on the back of the component (both SKyView displays and the three SkyView remote modules). All this wiring says in the plane when you pull the panel. All remaining Left Vital load breakers are on the left panel wing, Right Vital load breakers on on the right panel wing - they stay in the airplane when you pull the panel. Non-vital loads and associated switch breakers (landing lights, nav/strobe, Pitot heat, Start solenoid, Voltage Regulator, etc.) are on the side breaker panel.
Note - both the GTN-650 and the PDA360EX audio panel trays get rear supports. For the GTN this is a piece of aluminum connected to the bottom of the tray, the forward end having a nutplate. Support is via a single screw coming in from the baggage compartment. The audio panel is similar, but is supported via the cross tie below the panel.
Goal - never be on your back with your head under the panel.
