Quoted from YZRider926:
Yes. You need to have a 35" door to fit the non split base through a doorway if i'm not mistaken. I've been researching these and planned for it be my next purchase, untill MMR was announced. Who knows it still my be my next toy.
Not quite true.
The door to my basement is a standard 32" wide and I *almost* couldn't get the base down my lousy, horseshoe-shaped stairs. Scary. It was very tight but I angled it down the ~37" wide stairwell somehow.
