As of 2015, the average cost of just the cab of a truck from a reputable company ranges from $130,000 to 180,000. The trailer component costs anything from $30,000 to $80,000, and this is excluding the cost of wheels and fuel.
The price of big rig truck cabs is affected by many variables, and some good brands have prices as low as $80,000 for a new truck cab. Older models are available at much lower prices, such as a 2005 heavy duty Kaufman in the vicinity of $9000, a 1992 Peterbilt for about $14,000, a 1986 Kenworth for about $12,000 and 2006 Freightliner models for about $20,000.
The steep prices of eighteen wheeler trucks are justified considering the fact that they can put in 1,000,000 miles before they need a significant rebuild. The engines are designed to be able to run non-stop and typically have over 12 gears. A truck is a big investment, and decisions such as whether to buy a new or used vehicle and the budget for either must be carefully considered. The expenses to run and maintain a big rig truck are quite extensive. Usual expenses include tire maintenance, insurance, state and commercial driving licenses, oil, gasoline and engine oils.
