Updating this post: sold the Double Rainbow a week ago, but still have the 1-man version Tarptent Rainbow. It's an older model, probably about 10 years old, but still in good shape. Seam sealed and has held up in rain. I do not have any stakes for this tent any longer, so will need to come up with your own.
$140 face to face, or add shipping. I have pictures I can send if interested. Located in East Mesa.
