We live out 7 miles from a really cool, locally owned camper/truck topper/rv manufacturer. They've been around for ages & have a stellar reputation. I met the owner today, really nice guy. I walked away with a cool RV catalog about the size of the old Sears Roebuck catalogs...remember those? He also gave me a window pricing sheet. I haven't priced all options yet, but they stock everything on the list. At the very least, it gives us some idea of typical styles & dimensions. Thought I'd share. Sorry about the sideways photos.
