I've removed the pop top and installed it myself. Kind of a pain but
doable. You'll need some way to prevent damaging the fiberglass and
slipping off the gutters the wrong direction. I used a blanket, two
2x4s and/or heavy dowels and a ladder. If you have two people, one of
them will be weaker or not as committed as you are (or both) and so
you should use the same technique.

If I had 4 people to help me with anything... I'm not sure I can
really comprehend what type of person or life I would have.
