A Doo 154" actually has more footprint than a Cat 162", so it is a valid comparison. Gotta remember the Doos are 16" wide.The cat is only 20lbs heavier and its a 162 instead of comparing a 153 and 154. I thought the doo promotions said they were "way" lighter, it couldn't be doo using marketing tactics and lying..could it? They wouldn't do that sort of thing would they.
