Some people have asked about the monitor we installed in our Challenger. Here is a copy of my post.

I bought everything from
www.rearviewsafety.com. Here is the parts list from them. Also you will need 18ga butt connectors.

I tied the power supply into the incoming power wires to the dash fan switch. This makes the screen only power up when the RV is running or in the on position and it was the easiest to steal power from.
Unplug the wiring harness to the dash fans. Crank up the RV and use a volt meter to test which wires are hot. My wires were two of the multi color wires. Make sure you have correct polarity. Turn RV off double check with volt meter to make sure no volts before cutting. Cut wires about a foot away from the switch and tap into them with the power leads on the wiring harness for the screen. Once tied back together, make sure your dash fans still work.
On the back of the Axxera there is a video cable. Follow it backwards till you locate a black box with 4 inputs and one output. This is the video switch box. It is about the size of a deck of cards.
Unplug the 3 video feeds at the ASA connections. Note which ones are CA 1,2,&3. On my unit CA1 was left, CA2 was right and CA3 was rear. You might have to switch them back around if the wires are mislabeled or different. Plug the incoming video feeds into the screen harness using the adapters which are 5 round female to ASA female. At this point you can turn on the screen and make sure your feeds are the correct camera label on screen. Turn it back off.
Next, the 4th cable hitting the switch box is the trigger wire set. Follow it out from the switch box to the backside of a connector plug. There will be multi color wires before the connector and should be labeled CA 1,2,&3 as well. On my unit, the wire colors actually matched the colors on the screen harness. Hopefully they will on all units. Cut these 3 wires. Use a butt connector to attach each of them to their corresponding video trigger wire on the harness.
Power on the screen and TEST, TEST, TEST!!!
The blinkers on the RV should trigger the corresponding side camera. Shifting the RV to reverse should trigger the rear camera.
I unplugged the harness from the screen and then ran the cord thru the hole just above the left corner of the Axxera. This way you don't have to drill thru the dash cap.
Mount the bracket arm. I chose the flat spot just above right of the HDMI port. MAKE SURE THERE IS NOTHING BEHIND IT BEFORE YOU SCREW ON THE BASE!! I installed the screen on the bracket arm with the thumb turn facing down so you can get to it to tighten.
That should be it. Congratulations, you now don't have a crappy Axxera as an issue anymore for video feeds!! Lmao... Let me know if y'all have any questions... I tried to be fairly thorough. I highly suggest looking under the dash before ordering everything. As much as manufacturers switch stuff around, it would be a PITA to get all this stuff and not have the correct adapters, etc.
