Okay, let's hear it from the experienced hands here. We're all familiar with the notion that the first employee on your truck is more productive than the second. It may (or may not, you tell me) follow that a second truck will not be as productive as the first...perhaps mainly because the owner of the LCO is not on that second truck and they will tend not to work as steadily. I tend to think that there are economies of scale to be obtained with multi-unit operations, but I don't know how significant they are. Does the economic law of marginal inputs of labor/equipment yielding lower margins of revenue nonetheless prevail in this case?
