Hey, big congratulations! Hope you love your new purchase as much as we love ours (bought used in late 2010.)
Our house battery is also under the passenger seat.
I noticed that the style of fixtures varies among units I've seen in the 2005-2006 group. Our kitchen fixtures similar to yours, from the description. Maybe they just used them as they phased into different styles during that year. It's always fun to run into another 210B LTV when you are out traveling. We saw twins of ours in S. Dakota last year and on Key Largo this year. Instant camaraderie!
Will really look forward to hearing how it goes for you.
