Ahh yes Claudia! The joys of new RV ownership, "getting the bugs out"! I am chasing an intermittent picture on my rearview cam, seems to work when it wants to, usually at the dealership! My side view cams always work great. Ohh well, I have been an RV'er long enough probably like you, that we know it just comes with the territory!
Take Care & Happy Camping! Hope to meet you on the trails someday!
