Got it. Just a little hassle with Walmart. First, they had it in stock, same price, which was fine, they didn't have the screen so I was glad I ordered (even though obviously they did have it since they pulled mine off the floor.. weird store.) But they'd pulled a gray one, not tan, which I'd ordered. Then they had to refund the gray one and bill me for a tan one. I could have gone up front to the long line at customer service and done an exchange if I hadn't been able to have both on the credit card. I asked why they didn't fill it with the tan one and they said the codes were interchangeable- interchangeable to FILL the order, but not to switch across the board when they filled it wrong. Geesh.
The guys were nice and helpful, though, and since they don't make the policy I didn't get mad, just exasperated.
Got it home and set it up, and it cleared the door, even with the trailer facing up hill so that it's back was higher than usual. Wind was blowing too much to leave it up and try the screen,t hough, so that will have to wait. The screen is nice and lightweight. This canopy may become a sleeping porch if it gets hot this summer. I'm impressed by the quality- sturdier top than either my Quik Shade or my Ez Up, Metal is sturdier than my Quik shade and easier to work alone than my EZ up. Top has reflective material on the inside which does help if it is hot (here rain is more likely the issue.) And it does have ties to tie the top on and stake it- EZ up didn't.
