These problems are hard to find. You need to gather all the information you can. Make notes of when it happens, what you had on and what items are affected and how. You're going to have to play detective.
I'd agree the combo switch may be the cause, except for the backup camera poping on. The backup camera should not be wired to the headlight wiring other than to adjust the brightness of the display. If it's acting like it's been put in reverse, that's a great clue.
This problem may be above your average RV dealers ability. It sounds more like a "truck" problem than an "RV" problem.
I might change the combo switch just to rule it out. Sometimes you have to "throw" some parts at the problem. You can spend hours trying to find the problem but it may be more cost-effective to throw some new parts on it.
I'd also go over the grounds, clean them and add some new ones.
We see a lot of problems with instrument clusters.
