Another update.—l had nice 50 degree weather today so I crawled up under the coach and ran the new cable for the rear view camera. What I found was the existing cable (assume it was original cable) was run every where it should not have been. Through the spring shackle front and rear and over the steering box between the pitman arm.
The rear spring shackle sliced the cable clean through. I ran the new cable inside the frame rail and secured with many zip ties and far away from moving suspension and hot exhaust.
This job took about 4 hours crawling under the coach on my back and fishing the cable inside the rear wall.
Just to make the job more challenging I bought 100 zip ties from Amazon (made in China) and half of them had no teeth to zip.
Safety advice—I raised the left side of the coach with the Lippert jacks and put wood blocks under the tires and lowered the jacks and chocked the tires. This gave me enough room to crawl under the coach safely. Never get under the coach with only the Lippert jacks. That could be a deadly mistake.
