96 inches for the cab, and the dump body can be up to 102 inches wide.
Depends. 17 tons, give or take, is typical.
They're usually between 11 - 12 feet tall at their tallest point.
That depends on the dimension of the dump body. The dump body could hold 15 - 20 cubic yards of material, typically. As for what can legally be hauled, it depends on the commodity and weight of the commodity per cubic yard, as well as state laws pertaining to what weight limits they allow for a tri-axle.
Concrete is measured in yards, not tons. As for permissible tonnage on a dump truck, it'll vary by state. IIRC, in North Carolina, a tri-axle dump is typically good for 16 - 18 tons, dependent on tare weight, wheelbase, and whether they're traveling on primary or secondary roads.
The weight of the truck/truck trailer when it is unladen (empty) .
That would be the weight of the truck and the cargo.
GVW is gross vehicle weight which is different than GCWR (gross combination weight rating). Pulling a trailer weighing 10 tons should not cause you any problems. However I am assuming you have your dump tagged at a little less than 55,000 to avoid paying heavy use tax. Even if this is not the case and you have tagged it for a heaver weight be aware that pulling that trailer while dump and trailer are loaded may put yousignificantly over your tagged weight. Just watch your gross weight or you can re-tag your dump for 80,000. When GCWR is not available on the power unit DOT will add the GVW for the dump and the trailer to get a GCW (gross combination weight).
The weight limit on an ATV truck rack can be found on the websites that sell ATV truck racks. The weight would depend on the size of the rack & truck.
