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.
