Anyone ever remove trans & transfer case by themselves?

[Eyegore]

I have to pull a turbo 350 & transfer case. I've done it before but not by myself. Can it be done? I'll be using a floor jack trying to balance the trans and transfer case, the truck will be sitting on the ground, no jack stands, seems to be enough room. But in reality can I do this myself? Have any of you done it alone under the same condtions. By the way the last time I pulled a transmission & tc was some 20 years ago.
And I know the transfer case weighs some 250lbs or seems that heavy.
