Can I expand a little?
What about the roof? Will it handle the weight of you and the AC concentrated in the small area of your feet?
I used a couple of pieces of Styrofoam, set AC on to slide from side to hole. Step ladder in back of pickup to get it on roof, with line around it. Up another step ladder to pull across near hole. Then a stepstool inside to lift and guide it into the hole.
Another idea. To me, holding the inside part up, aligning and starting the longdonkey bolts was a PITA. Cut 2 pieces of all-thread little longer than bolts, screwed into holes. But the plate up, EZ to guide AT thru holes, start nuts. Then nuts hold in place while you start the bolts in other holes. Double-nut the all-thread to remove, last 2 bolts.
Typically the roof will support you and the AC as it has to support the A/C all the time anyway.
I've personally changed out several A/C units and have never needed any allthread to do it. Bolts went in easy. If not, the A/C is not located correctly.
I have often had to work to get long bolts started when they go thru something thin, had no support guiding to holes, like putting thru bolts in motors. The top part in hole, but on mine the only guide to position the bottom part is the bolts. Add that to the issues many old people have working overhead... With the all-thread, just like putting a album on turntable, or the top on old air cleaner. Look thru hole to see pin, watch it into place.
Now I found using rod for alignment made it much easier. And I found that setting the unit overhanging the roof hole, but propped up so I could lift and align from below made it easier to position without push gasket out of place
