Not only a similar problem, but almost exact. I've removed and installed a few window unit air-conditioners in the past, but a couple of years ago when I put the 12,000 BTU unit in the shop, I did the framing and installed the case, but had to wait on a younger brother to come visit to help me lift the unit and put it in the case. And I recently had to move some folding tables. The largest one is something I can carry by myself, but it's tough. So I told my son-in-law to get one end and I'd get the other. Danged 39 year old kid said, "I'll get it", grabbed it in the middle and walked off with it like it was nothing.
