I don't think I would ever run one man crews for reasons already pointed out. More trucks, equipment ect. Also, I think it would bring that one man down knowing he has to do everything alone. Most guys like to have someone to talk to and share the work load. I think it keeps them motivated. Two man crews seem to be working for us. I think anymore than that is overkill unless it's very large properties. I have considered three men at times, depends on that days route, but never four.
