Welcome to the forum and congratulations on your choice of the best Escape model.
For years when I owned a 19 I discounted the "arguments" about which model had a "better" layout. But I have to say, there's nothing quite so nice as backing into a lakefront site and having a panoramic view out from the dinette.
The rally is very popular and space is limited. We had some uncertainty about our ability to attend this year and were lucky to get a spot. So book your spot as early as you're comfortable with.
