Overall, we're really happy with the Eezi-Awn on our Horizon. It stood up to a night of very heavy winds with gusts to 50 MPH winds on a trip to Canyonlands last year. I think they may a little more expensive than some other brands, but I think the quality is there.
BTW, we can lift the lid on our Horizon when the tent is deployed. The only issue is that it can be a little fussy to get the two halves properly aligned when you close the lid. There is a metal lip on the half mounted to the trailer that should slide below the other half of the tent. When you close the trailer lid that often won't happen and you need to lift up the other half and push it onto that lip. Not a big deal, you just need to remember to do that if you have the lid open.
