I was lucky to have the shorty Rohn 25 top section. I was able to install
the plate, rotator and short mast in this section on the ground.

That is the intended location of the rotator and plate.
Does your top section have such an area?
I found many areas on my 25G where I could tip the accessory shelf and
insert it diagonally. It was necessary to move it vertically to find a
spot where I could out the "U-bolts" to hold it. I don't remember for
sure if I put it in aligned with the legs, or rotated it to align
afterwards. The shelves on all of my towers are smaller than the space
between the legs. On the 45G, to get a tight fit I had to make 1/8th inch
spacers for each leg, I didn't for the 25G, but it was what I'd call a
loose fit.
The easiest "points of entry" are at the junctions of the 10' sections
As Gerald mentioned the place in the top section with no cross braces,
such places exist at the junction of each section. Personally, I don't I
don't like mounting the rotator close to the top. My preference for normal
installations is at the junction of the top section and the next one down,
but there are many places where you can insert and mount the shelf. For
me, the shelf was the easy part.
My problem was getting the Ham IV into the tower. Apparently there are
some variations in the diagonal bracing. I don't remember if the gap is
large enough at the junctions of the sections, but if it is, you could
insert the rotator, raise it up enough to get the shelf under it, mount
the shelf and then set the rotator on it.
