basically like that


and if it is a light load you use elastic tension belts, if it is a heavy load that definitely can overpower the force an elastic tension belt can endure you use chains, also, rubber mats under the load reduce the requirements on the elastic tension belts and are also approved load securing accessories (i bet also allowed i nthe US), or any form of loading that hinders slipping, like putting pallets, that are secured ofc, in the front between tank and gooseneck so that there is no gap to slip into, in Germany we would say form fitting load securing* (Formschlüssige Ladungssicherung), loading cargo so it cant slip by putting it right in front of the boarding wall for example, the other loading method would be frictional load securing* (Kraftschlüssige Ladungssicherung), preventing with rubber mats, elastic tension belts or chains that the load can slip off
* dont know if those are the right english words for the German equivalent of them, so if somebody can correct me here you are welcome to do so
i know it isnt always easy to find a proper way, i had to really think about it when i made a new cargo model



but securing the load right is everything and shouldnt be an afterthought
