Rotisserie Advice needed.

Has anyone installed their engine, transmission and rear end while the car is on the rotisserie. My rotisserie has a posted max. of 2,000 lbs. I crunched the ball park numbers of the 360, “K” & A518 and I think I’m OK. I have a disability and it is very difficult to get up and down off the floor. It would make my life much easier to fit and form on the rotisserie. Safety first! I don’t want the car to fall on me or anyone. What are your thoughts? Anyone?
