Alot of iron easily comes off the stove.
You can remove the six round cover plates on top and usually four of the pieces those plates rest in, called "I's" and "T's" because of their shapes.
The doors to the oven, firebox, and ash drawer usually just lift up and their hinge pins come out of the gudgeon (the half of the hinge that's cast into the stove).
And the back splash and shelves are usually just held on with several small machine screws.
Any swing-out trivets lift right up and off the back splash.
The stove body lifts off the base skirt and legs.
So, that means that about 1/3, or more, of the stoves weight can be carried into the cabin in small pieces.
I'm your age now but, when I got my kitchen range eight years ago, after removing all the loose pieces, I brought my stove body in by myself using a cheap hand truck and some rope to tie it to the hand truck.
