A tandem dump truck is as normal as any other dump truck. Tandem simply indicates that it has two drive axles (as opposed to a single axle, which only has one). A tandem dump is typically allowed to gross at 54,000 lbs. From there, some dump trucks have additional axles (lift axles) which allow them to haul more weight. They're named in accordance with the number of axles behind the cab (i.e., not including the steer axle). So a tandem dump with a single lift axle would be referred to as a tri-axle, with two lift axles it would be referred to as a quad axle dump, with three lift axles it would be referred to as a quint axle dump.... at four lift axles, they're typically referred to as 'centipedes'.
A tandem truck is a truck with two drive axles.
The difference between a normal GPS system and one made for trucks is that a truck GPS system also includes routes specifically for truckers to drive on.
An armored vehicle is reinforced on the body with bullet proof steel or metal.
The "tandem" part means it has two drive axles, although it is possible for a tandem truck to be a 6x2 vehicle, and have only one of those be a live axle.
A dump truck with two drive axles.
Depends on the motor, drivetrain, and how it's being operated. Typically, you can expect between five and seven miles per gallon in normal driving while loaded.
A tandem dump truck typically holds between 10 to 16 cubic yards of gravel, depending on its size and configuration. The exact capacity can vary based on the truck's design and the density of the gravel being loaded. It's important to check the specific specifications of the truck for accurate measurements.
You need to be more specific about the configuration. Is a single axle straight truck, a tandem axle straight truck, a tandem axle straight truck with additional lift axles, a tractor trailer...?
A truck load of topsoil
The emblems.
A standard tandem load typically holds around 10 cubic yards of material. It can vary slightly depending on the specific dimensions of the truck bed and how the material is loaded.
Need more specifics. The T800 was available both as a truck tractor and as a vocational truck. There'll be a substantial weight difference between a tandem truck tractor and a quad axle cement mixer, just as an example. All things dependent, you could be looking at anywhere from 15,000 to almost 50,000 lbs. tare weight.
