How did you install your Garmin camera?
Garmin BC20 "Wireless Backup Camera" The power cord coming from the transmitter box is super long, but the non-weatherproof fuse holder and camera connection are short. What's up with that? I fi...

We bought the BC-20 camera and also the extension cable.
I welded up some scrap steel and made a mount to sit on the bumper. There is absolutely no place to mount the camera on the rear wall without drilling through the fiberglass, which I am not going to do. The camera does not have to be in the center of the TT and the mounting height isn't critical as the image is adjustable on the screen for left/right and up/down.
The connector is a bit of an issue because it's not watertight - not sure why they do that. I used some heat shrink tubing on the connection. I ran the wiring from the camera to the ceiling via an interior wall at the rear wall of our TT. Then I fished the extension cable through the ceiling to the storage cabinet above the bed where the transmitter is.
I also ran a wire from the junction box in the A-frame to the transmitter so that the camera is activated only when the truck is in reverse. There is no way to get a wire from the junction box to above the bed without pulling down the underbelly sheeting. So I ran the wire underneath the coroplast and zip-tied to the gas pipe and then up into the ceiling at the rear of the trailer and then along with the extension cable to above the bed.
The camera does work, but... Once in a while the image does not come up on the screen. Kinda strange and will have to check connections on the power wire. What really bothers me is that the image on the screen is quite grainy and to the point that it is hard sometimes hard to see what's really happening at the rear of the TT. It might be due to the length of the extension cable and too much signal loss? There are some reports on the internet of some folks having a poor image too. Also, with the grainy image, it's harder to see in bright daylight even with a sunvisor/hood on the screen.
