Many congrats on your new RV. I hope you have many happy years in it.
Two months ago We just bought our 2016 Lance 1995 and I'm systematically going through every conceivable upgrade I can think of to make life easier with it.
I honestly think if your not comfortable doing the electrical, get someone qualified to do it. Do not mess with this area. It just makes sense. And yes, if it's at the dealership then get them to do it as if anything were to go wrong, it falls back on them.
Anyway, once again, we'll done and pls post pics of you and the family when you can.
