Dump trucks are handy vehicles that are commonly used to transport things such as rocks and dirt for construction and landscaping. Dump trucks are characterized by an open box bed of the truck with a hydraulic hinge at the back allowing all the “cargo” to be deposited behind the truck. Different Kinds of Dump Trucks You can find many models of dump trucks. The classic one is the basic truck characterized by an open box bed with a hydraulic hinge at the back. There are also articulated dump trucks that have hydraulic rams for steering that allow the vehicle to pivot. Articulated dump trucks are called Yukes. Transfer dump trucks are a standard dump truck that pulls a trailer. The second trailer can also be filled with sand, gravel or snow. There is also a triple transfer train that can be found in this family of dump truck. Transfer trucks are often seen in the western part of the U.S., but the triple model is usually not seen outside of Nevada or Utah. The truck and pup is another kind of dump truck. This truck is a bit like the transfer dump truck, but unlike the transfer dump truck, the pup trailer has its own hydraulic lift. A super dump trick is a normal dump truck that comes with special weight bearing axel. This axel is called a Trailing axle, and the dump truck portion is generally about four meters behind the rear tandem. Semi-Trailer Trucks Other models of dump trucks are the semi-trailer family, which come in different varieties. The semi end dump trailer holds a hydraulic hoist. Its advantage is fast unloading. It is limited because it is unstable when dumping. The Semi-Trailer Bottom Dump Truck has a special gate at the bottom center of the truck for unloading. This type of truck can also come in double or triple versions. You can also buy side dump trucks that load out the side and unlike the above trucks they are not likely to tip over. For heavy construction, there are the off-road dump trucks. These are used for heavy dirt hauling and mining operations. Lots of models of trucks make up the category of dump truck.

A semi-trailer, as opposed to a full trailer, means it only has axles at the rear of the trailer and a full trailer has axles at the front and rear of the trailer. We call these in the UK "drags", as in wagon and drag, where the wagon that pulls the drag can carry a load on its own, whereas the semi-trailer truck, or tractor unit cannot carry anything without a trailer.
There's no need to - just don't push in the trailer supply valve. If you want to plug the trailer supply lines, you can.
