We used a ladder as a ramp. I had a nice solid cardboard shipping box from my new dishwasher. It was the perfect size. Opened up one side, set the ac in it (on 4x4's to protect the aluminum cowling), wrapped it up tight with ratchet straps, and my neighbour pushed while I pulled the thing up the ladder. Once it was up there it was very easy to maneuver around on the cardboard. It went pretty smoothly, surprisingly.
Actually, given all of the many potential problems I could have encountered, the entire process went well, especially since I was doing the whole thing myself. The only help I had, was getting it up on the roof (and a neighbour - retired electrician - standing by to pull me out of the trailer if it all blew up in my face when I turned it on
). The old vent was screwed in, not riveted, and they were Robertson screws 🇨🇦, so the bit easily grabbed the screw heads, even if I couldn't get all of the old dicor out.
The only hiccup was the old antenna mount. It was about 1.5" too close to the end of the ac for me to move into position. So I finally had an excuse to remove it. There hadn't been an antenna up there in years. Fairly easy to take out. Most of the dicor around it was still fairly malleable. Took the whole thing right down to the roof. Was left with about 10 little screw holes and 2 half-inch holes in the centre. Cleaned the gel coat up well, and covered it all with eternabond. One day when I'm in the mood, I'll go up and replace that with some epoxy and make it a little neater.... or not. It is the roof after all. I needed easy, quick, and reliable at this point, and I had the eternabond. If I was willing to leave that ugly antenna mount up there, just because it wasn't leaking, I think I can happily live with a few strips of eternabond tape.
A total of 3 days, working about 3-4 hours a day with lots of short water breaks - too hot up there right now. 29C in the shade, and there's no shade up there! So I'm patting myself on the back a bit (if you can't tell). Cleaned the shroud and the ceiling cowling last night and I'll pop those on this morning.
