If one bases the arrival and landing weight of each aircraft on it's maximum landing weight, then the matter is irrelevant...it's not going to be any heavier if it's tankering fuel, if the stress analysis is based on each operation at it's maximum weight. "Heavy" and "light" are relative. We generally always depart at maximum takeoff weight, and land at or around maximum landing weight...what percentage of the fuel load is tankered, then, is irrelevant to the considerations of runway or taxiway or apron life.
