We have 2 different canopy solutions.
For fair weather camping, we use the Quickshade Summit 170. It's a 12x12 with extensions that can be folded down on 2 sides for 1/2 walls or extended out for extra shade.
For wet/rainy camping, we have the Northern Breeze Screen Tent. It is also a 12x12 tent with extensions that can be put down for full walls or extended for extra shade.
We only bought our trailer back in Oct. so have not really done any wet weather camping and therefore not yet used it...there are several others with the CampInn trailers that swear by this shelter. However, it is pricey at $400.00 for a new one. Ours came with the trailer so we did not need to buy one but it is light and fairly easy to set up. The quick shade is easier but it is also way heavier.
