The extra length in an Expedition Max or Navigator L buys you a real cargo well behind the third row, and that is exactly where the groceries, the gear bags and the muddy cooler go. This WeatherBeater liner covers that well with a molded thermoplastic floor.
Coverage stops at the back of the third-row seat - it is sized for the space behind those seats, not for the full load floor with the seats down.
Standard-length Expeditions and Navigators use a different part. This liner covers the cargo area only - no front, second-row or third-row floor coverage.
