To my neighbors' amazement, I simply left the replacement Courier A/C in the box and PUSHED it up the ladder to get it on top of the Argosy. It almost killed me.
Airconditioners never need replacing when it's 70 degrees out there. It was 100+ on top of the trailer. This turned into a crash course in "getting it running NOW - worry about finishing installing it later."
I also made a 2x2 wooden frame for it to rest on. Unfortunately, I didn't hook up a new drain - I bought into the idea that most of the runoff would be slung onto the coils. Bad idea. Runoff gets slung THROUGH the coils, and then it runs off the side of the trailer. I need to correct that one of these days.
