Brian, Congrats on your 2017 and yes you can contact Fleetwood. We picked up a 2016 Excursion 35E last May and over the past four months amassed a lengthy list of minor issues, some more minor than others. I made an appointment at the factory service center since one issue required someone who understood where all the cables for the TV ran and I figured who better but Fleetwood. As for my dealer I wouldn't let them touch it because I was afraid of exploratory surgery on their part. Anyway, Factory Service center is teh best. Can;t compliment them enough. They worked through my list over three days and got it all done. Even ended up replacing the front face of the vanity because of a water leak in the ice maker. Many of the items on my list were no more than questions which they readily answered. I was allowed in the shop while they were working so I got to see how it all went together. It was worth the 10 hour trip to spend a few days there. Its CRITICAL that you make an appointment before going. You'll be seen right on time and its easier to plan a trip. You can just drive in unannounced but might wait a couple of days to get in the shop and even then you will be limited to three items. With an appointment they will do it all in that visit.
My dealer also was challenged when it came to describing the coach and I've contacted Fleetwood directly a number of times trying to locate things I couldn't find. From the Fleetwood website select Parts and Service/Order Parts/Contact us and fill in the form. They usually respond within 24 hours and often will send teh final build drawings so you can trace somethings yourself. A great service.
Also consider putting more questions in this forum. Usually someone knows the answer.
As to your battery question I can't say as the 2016 we have only has 4 house batteries and our location on the chassis might be different from the 33D. There were some chassis changes in 2017 so that one may be best left to the FSC.
