I'm not a fan of the side-mount roll-up awnings found on most RVs. The basic ones just aren't that good, and they cost a fortune.
For $300, you can get a nice 10x10 easy-up tent - get the commercial, brand-name one, and it takes one person to set up, and you don't have to duck to walk under it. Make sure it has the straight up and down legs (not the angled ones.) You can set up two (or more) next to each other to make it bigger too.
They make them with solid sides (so you can block whatever side the sun is on), or you can get screen sides - so you can actually sit outside and not get eaten alive by bugs. If the wind or a freak storm comes by and does damage it, you're only out $300 - not $3,000 for a replacement. There's no drilling, tools, or custom installation.
My friend has a big awning on the side of his RV, and in the span of a week and a half, it felt like we were CONSTANTLY running back and forth to the RV to roll it up again before it rained, or high winds came through. We actually missed it once, and it filled up with water. . .we estimated about 150-200lbs of water. When we tried to let it down to drain, it came down with a crash, and bent the bar that the canvas rolls around. It was around $3k for a new awning, with his insurance actually covered - since it was the water, not the wind that actually did the damage.
I /might/ also have a bad habit of leaving his RV, closing the door behind me, and promptly walking into the front support bar of the awning. . . .
