After just about two years, I’ve sold the topper:
Compared to the pop-up campers, it was a much better compromise for a daily driver. I ended up not camping out of it that often, but when I needed to it did well enough.
For the rest of the time, it did it’s job of generally keeping things dry and out of sight. I ended up selling it for the same reason I swapped out the tires and rims, it’s time for a new project.
