I don't have pictures but two wolfpacks will fit side-by-side ("sideways", so the widest orientation) between the wheel wells with no issues. The wolf packs are 20" wide and between the wheel wells has about 42" i believe. the height makes them just about equal to the wheel wells when placed on the cargo tray. cars without a tray or with third row seating will have different heights.
If you have a sliding cargo tray you can fit four wolfpacks on it and still operate the latch at the front without issue
