When should I add a second truck?
Short answer
When your first truck is booked out more than a week and you're turning away same-week work, not when you're just busy. Run the math on what the truck needs to bill before you sign for it.
The real signal isn't how tired you are
Owners add trucks because they're exhausted, not because the math says to. Exhaustion means you need a dispatcher, a better schedule, or a day off. A second truck means you have proven, recurring demand that one truck can't absorb.
The signal to watch is your booking lead time. If you're consistently booking six or more business days out on non-emergency work, and turning down calls because of it, you have real, fundable demand for a second truck.
Do the math before you sign
A new truck and tech is a fixed cost the day you commit to it, whether or not the leads show up immediately. Work out what that truck has to bill per week to break even, then be honest about whether your lead flow supports it starting in month one, not month six.
Second truck break-even
| New tech loaded wage | $1,400/wk |
|---|---|
| Truck payment + insurance + fuel | $450/wk |
| Tools and marketing allocation | $150/wk |
| Total weekly fixed cost | $2,000/wk |
| Target labor margin | 45% |
| Revenue needed to break even$2,000 / (1 - 0.45) | $3,636/wk |
The math: Weekly fixed cost of the new truck divided by (1 minus target margin) is the revenue that truck must bill weekly just to break even. Compare that to your actual backlog of turned-away work.
Before you add a truck
- 1.Track four straight weeks of turned-away or pushed-out calls, by dollar value, not just count.
- 2.Confirm your booking lead time is 6+ business days on non-emergency work.
- 3.Run the break-even math on the specific truck, tech wage, and market you're hiring into.
- 4.Line up the tech before the truck, not the other way around.
- 5.Have a plan for the first slow month, because new capacity rarely fills on day one.
Where owners get this wrong
- Buying the truck because a good tech became available, without demand to support it.
- Assuming marketing will instantly fill the new capacity.
- Not budgeting for a slow ramp-up month.
