Here's a quick and easy dash cam install I did on my RHO in about 20 minutes. All you'll need is a plastic trim tool to remove the rear view mirror housing. Please note this power method only works while the truck is running or accessory mode is on. If you want it to power while off and in park this method is not for you.
I used a Viofo A229 Pro cam, but this install should be able to power other dash cam make/models. The key component is the Dongar power harness (which comes with the plastic trim tool). Note: It comes with a USB-C, Mini USB, and Micro USB in the kit but you'll most likely need a longer one then what is provided depending on camera mounting location.


I found the Dongar on Amazon for around $40
Step 1: remove the rear view mirror trim. It's 2 pieces. Start by removing the piece in the middle then the outer housing. It pried off very easily.
Step 2: find the power dimming mirror harness and push the tab in to separate it from mirror.


Step 3: connect the Dongar harness inline with the vehicle harness. It can only go one way. Arrange your harness how you like. I found going up over some wires best.


Step 4: reattach your trim and snap into place


Step 5: figure out where you want to attach your camera. There is a flat portion on the mirror trim that I'm trying out. When sitting in the driver seat the camera is behind my rear view out of site. I might move it to a more traditional site later but I just had my front window tinted and didn't want to use the double sided tape on it.

And that's pretty much it! The rear view camera still works as well:
