Here you go. The first photo shows my slide topper on the slide with an awning; in my case the kitchen slide, in your case the dining slide. The second photo shows how the slide topper brackets are designed to be installed. Note they are inside the flange so there will be backing to screw them into. They cannot be screwed into the flange; will not hold. The third and fourth photos shows how I put them on. I simply drilled additional holes in the slide mounting brackets to attach them to the solid part of the slide. Since the slide brackets sit on top of the flange, I used spacers between the bracket and the slide (inside the flange) to account for that space. I have the same amount of fasteners on these modified brackets, just in a little different place. These toppers have been on for over two years, two cross-country trips and a trip to Alaska; no problems.

If Keystone would have put the awning a couple inches lower, it would not interfere with the slide topper brackets. In my case, they could not because of the refer vent, but I don't think there is any reason they could not have lowered it a little on a dining slide. Guess that is water under the bridge.
