Is there an ideal side for the dinette?

I've had both. Yes-the dinette window is typically one of the largest windows-so do you want privacy or do you want a better view of the campground. Curbside is nice when we family-camp in our large group and want to see who gets up the earliest (Us-obviously-otherwise we couldn't see who got up the earliest), or who just got back, or whatever. Streetside is nice when your neighbor is a new camper and is learning how to use all his equipment-great time to remember some of your own old stories-things you would miss if you were sitting around the campfire. I could ramble on because there's smores but there's smores. :)
