I really like the build quality & ease of set up on the EA 1800, mounted on my AT Horizon, but if I had to pick one nit, it would be the design of the mini awning over the door. It is real functional as long as it isn't windy, but if you have a strong wind it flaps all night long. If it isn't raining or you are in warmer climates, you just leave it extended or you can roll it up, but with windy, cold weather, storm conditions, and you try to button the thing down, the wind gets under it and lifts it up to the extent of the toggles and then it snaps back down - this goes on all night long.
Really wish they would have had it designed more like a North Face mountain tent, and use a small pole/sleeve along its sides to totally secure it - really annoying in the wind, and I see this as a significant weakness in the tent design.
