If I have to work on a stacked unit and remove the dryer, I usually bring a second man. I don't like using the homeowner. If an accident occurs and they get hurt, that would not be good. I'm always thinking about liability. If they don't want to pay for second guy, I'll turn the job down. Not worth a lawsuit. You guys have to start thinking of that. If they get hurt, they'll blame you.
That stand looks good, but takes a lot of room in the truck and I prefer to have the second man as it is safer. I do have a small stand I use for double ovens, but again, depending on situation, I'll bring a second man.
