The Smiths, Greg and Rachel, are another DSM-area couple with an A122BH. They have a 2013 model. They're camping at Jester this week, until Friday. Just thought I'd mention it if you wanted to compare notes with a similar unit's owners. Don't know their site number but they should be easy to find.
It's never too late to have a happy childhood!
