Acting on these recommendations, I ventured into the local WalMart and bought one too. After a long weekend in and around Rocky Mountain National Park, I returned it for a refund.
Part of the problem was that I didn't buy the model mentioned here, but another Ozark Trails screen house of the same size that was featured for $35. It had a double hipped roof, not the single arch, and because the roof was tan instead of black, it didn't cut provide very deep shade. It would have been a great light-softening screen for outdoor portrait photography, though.
The screen room setup wasn't so hard, but then a gust brought the thing down, hitting my daughter on the head with a metal pole. This square, florless room doesn't have the additional structure provided by a tent floor, so it only stands as well as it's pitched. IMHO, for a sturdy pitch with any of these large rooms, you need to double-stake the corners. Instead of running a single guy line to a stake at each corner, use two lines at each corner, running at tangents to the walls. That secures the structure from twisting in the wind.
I tried the room beside my 16'
Scamp, but it was a foot too short for the trailer door to open into the room door. The room & trailer were too wide for the standard gravel parking/camping space I was parked in. Using the screen room's other door meant walking on wildflowers, definitely not low-impact camping. As my 9-year-old said, after her head stopped hurting, "It would be better if there were doors on the ends."
It would be better, too, if it had opaque walls for privacy. So I've decided to go back to using a large dome tent, 10 ft diameter and 7 feet tall, for these duties.If I camped in buggier climes, though, I might feel differently.
