Gear width
Someone who has theirs right out in their garage can measure exactly for you,
but I remember it was about 81" or so. I am positive it is less than 84".
If that is too wide, you may still be OK. Without the axles and wheels on, the ends of the gear legs are probably less than 72", so you could make some little wheels that bolt right onto the gear legs (on the inside) to roll it through your doors.
So, someone, maybe verify the width to just the outboard faces of the gear legs as well as the total width.
