Well, I don't have a leaf vac but my plan would be to completely empty out my 7x14 except for the Z/bagger and dump in the front end of it on a tarp and park the Z behind the leaf/clippings pile. Should be able to dump a fair bit of material up there, at least a half days worth when I can go at lunch and dump, and then do another half days worth and dump at the end of the day.
I have seen the ease of the DFS but am not certain it would be an advantage unless yes, you have a loader system. I would not plan to dump on-site at too many homes unless they have wooded areas which not many of mine do.
