Whatever it weighs. You could be talking about a tractor-trailer unit, or a single vehicle, either of which in a number of configurations, and corresponding weights.
150 pounds....
Gross vehicle weight means the total weight of the vehicle itself, plus cargo, passengers and fuel.
Subtract the estimated weight of fuel and passangers from the vehicle's rating.
No. Some trucks list the allotted gross vehicle weight on the side, and some might even list the tare (empty) weight, but the actual weight of a truck (which is ever changing as fuel is burned off and different loads are taken) isn't put on there.
Yes.....
From 100 to 400 gallons, depending on how the truck was ordered. If you carry more fuel, you can go farther, but if you carry less fuel you can carry a larger load since they go by the total weight of your truck, including cargo and fuel.
Impossible to answer ! That would depend on the weight of the truck, road conditions, weather, engine efficiency... etc.
A fuel truck....
It depends on the weight of the truck and how it is used. The fuel economy can vary from ten to twenty mpg.
depending on the truck, the weight of cargo etc . the fuel milage can be anywhere from 4 mpg to about 9 mpg
Subtract the actual weight of the truck from 26,000 lbs (GVWR) to get the weight you can haul. This is assuming you are talking about a single straight truck with no trailer. It would be best to actually weigh the vehicle with full fuel tanks to get the most accurate measurement. You can get a weight at most places that sell gravel, stones, etc.
The "gross" weight of the truck and its cargo cannot weigh more than 26,000 pounds. This includes the weight of the fuel, driver, and any equipment on tne vehicle.
