The total price for a tractor trailer can be $260,000 or even more!
The average price for the cab alone (where the engine is, and from which the driver controls the truck) is in the area of $130,000 to $180,000. The cost of the trailer is another $30,000 to $80,000.
Some of the reasons a truck is so much more expensive than a passenger vehicle is the ruggedness it requires. While a car engine may be designed to last for up to 200,000 miles of driving, a semi engine is designed to run non-stop, and drive at least 1,000,000 miles before needing to be rebuilt.
Right now cities around the country are using tractor trailers to gather and distribute food to victims of Hurricane Sandy in the Northeast.
