There is many possibilities and it’s impossible to tell you with any certainty what exactly is wrong with your truck that is causing this issue.

With that said, it sounds like the dealer is going after the intermittent reverse light issue which WILL cause an issue with the rear view camera. The reverse light signal voltage comes from the under hood electrical center so there very well could be an issue with that center that is causing your issue.
