I have seen several RV/trailers that have a slide in the middle of the awning I find this kind of a bother because it does/could take away from area under the slide.
Yes you could put the slide in while the awning out.
Anyway the awning should clear the slide when deployed.
Try putting the awning out first then the slide while checking for clearance issues.
