Suburban Lift-Off Questions

[Street Sweeper]

We're getting ready to lift the body off our '65 Suburban. Ive seen some threads recently about cab lifts and rotisseries. Obviously the Suburban body is a little tougher to deal with.

I guess I'm looking for help from someone who's done a frame-off on a sub -

1) What's the best way to lift it?
2) Are there things I need to do beforehand to make sure I don't twist it or tweak it?
3) For those who have done it - are there things you wish you had done differently?

Any help is appreciated. To say I'm in over my head is an understatement - but diving right in is the best way to learn to swim . . . I think . . . right?
