engine hoist will work.
you don't have to raise the unit high.
Just an inch or two off the floor is all you need.
I'm probably not familiar enough with your TM to recommend the right lifting sling attachment points.
Get them set right, and it'll lift right up straight.
I've made mods to mine to make it easy in and out with a chain hoist.
My Powermatic's aluminum tube frame makes it easy to do that.
I roll it right out onto a heavy table I made to be the same height as the van floor
Before I had a PM I used a spud bar to lift and place 3/4" pipes under the frame so I could winch/roll it out onto a the table.
That might work for you.
Hardwood dowels or even wooden broom handles can be substituted for the pipe
That was some what of a PITA, but it worked and allowed a BDCC like me to get it done by myself
