Additional responsive CSS issues on Detail page

On the detail page:

The map is not expanding to full width at the point where other items are being stacked (tablet)

The tabs are stacking, but should we use a hamburger view for the tabs instead? The vertical space taken by the tabs is expensive.

If one or no images have been uploaded to a listing – you are left with a block of whitespace in the area which should be filled with an image. If no image has been uploaded and the listing is using the default (no image) – hide this area on mobile. Or, if only one image has been uploaded, use that image. It appears to be pulling the second image into this area.

Here’s the video to demonstrate:
