I rececently move my TZ into my basement alone.
I took off the head, and brought it and the body down with my escelara. I won't lie - it still scared the hell out of me (I'm 48 but in decent shape).....the first step off the landing to my basement isn't wide- and I have to push about 2/3 of it off the top to tilt the escelera....that's some scary shit right there...but got it down safely...
Not sure how many moves like that I have in me on my own!
