Won’t two men be enough?

Having the right team for the job is important. Nobody works well when they’re overwhelmed. Three men on a larger job is much more efficient than two. With two men carrying and one man loading, no one is jumping in and out of the truck and this means the pace is maintained. If your move is “bigger” or the access is “difficult” ask for three men. The hourly rate will be a little more but the cost is likely to be less.
