Since your under warranty THIS is the best thing to do. Everyone loves to "guess" at a problem. And that's exactly what it is a GUESS. If you start to tinker with the coach/genny under warranty you MAY put your warranty in jeopardy.
Since this is a 2014 MH and your not 100% about the total operation of the systems, then I think your making the best decision. Now, what I would do while I was there is work on getting someone to take you thru the coach and explain as much as possible about all operations if this hasn't been done. If this has been done, then get a refresh on things you don't understand. Even spending a few dollars to have this done COULD same you even more down the road.
Remember, nobody on this forum is an expert and we all have learned about our on coaches over time. If this is your first MH, then take sometime to read the manuals and ask your dealer questions.
