The cab overhang had to be left off for access for the operators. As built the cab was 10" lower so that ones head stuck up just over the cab roof for visibility. It was raised at the owners request. Visibility is now not quite as good but again its in the eye of the beholder. Anytime something gets small there are compromises. A lot of the Maine two foot stuff were hard on your scalp.
