I have the reimo, not really used it properly yet. I have a tailgate spoiler which affects how it sits, also think the gap between tailgate and body on the roof would let in a bit of water.
We got ours to use just a a quick shelter for overnight stops to sit out if raining / cook in etc, and it seems good for that.
Really compact and quick to put up.
We use an air drive away if longer stops ( 4 of us in a day van)
