Recently I have been asked by a couple cleaners "what is your formula for adding another truck, when is it the right time and how do you add another truck"? I have built to 5 trucks twice. The 1st time I built it to 5 trucks and sold it in the '90's. Then I built it again to 5 trucks after selling my business. I currently am at the same spot, the sweet spot. At least for me. Also TMF happened, maybe why its the sweet spot for me. And just for the record, if someone wants to stay one truck O/O there is no shame in that game. So back to the question, what is the formula and when is it the right time to add another truck?
