Bulk titan variant boasts full width hold on the front, but still only has narrow excavator, despite most of its frontal surface being free of equipment outside, and, in this variant also of internals (because it's all cargo bay).
Why not just punch multiple openings on the front and install grinders on them?
It will both give it more distinctive loook, unique gameplay "feel", and frankly make more sense than keeping tiny excavator matching original's narrow hold.
