This is too funny. We had the same issue. It's like a special needs person designed where those light switches go...not to mention the antenna booster and the speakers.
On the first trip out with our 30HDS we deliberately went from switch to switch at night time with me walking around the camper and the wife flipping switches while I figure what does what.
Of course I am an idiot and didn't label anything so we will probably end up doing it again next season.
