Side &Rear Cameras
I have a 2016 Thor Chateau 31L and had this problem.
There is an inline fuse under the hood of the truck that may need to be replaced. There is either a red or yellow wire going from the battery towards the firewall. I recently replaced mine and it fixed the problem. Also, if you have an Exxera radio it could have had an internal short which means you would have to replace the radio completely which I am doing currently. I'm told the Jensen VX4022A is a direct replacement radio. Hope this helps.
