We traded in our 2010 19H recently and I have a few leftover items that might be useful to others
PopUp Gizmos - high wind version. Used these a lot and they are still in great shape. I don't have the little clamp things anymore but we've been using binder clips and they actually work better.
Iota IQ4 Smart Charger plug in. Makes the standard Iota power converter a 4 way charger
like this one
I'm asking $50 for the Gizmo's plus shipping and $10 for the IQ4 plus shipping
