I bought this for pretty cheap at an auction and I don’t even know if there are instructions inside. I’m a pretty handy guy with time and tools and some knowledge. I’ve worked on roofs before and know the basics of many other trades.
If you don't have it already, get some mechanical help for heavy lifting and holding. It's technically possible for a single person to do a lot, but not if they crush themselves trying to hold up something that needs a machine to lift. If it's ever a fight, you need help, whether it's a person or a machine.
