The deployment mechanism can include a crane, a robot arm, a forklift, straps, and sails. The delivery container can include visible, partly visible, or hidden security features and grasping features, and can be foldable and stackable. The trailer can include a 4-bar linkage, the 4-bar linkage enabling consistent pitch between the trailer cargo and a cargo hold of the towing vehicle. The trailer wheels are decoupled from the 4-bar linkage, connected by swing arms and possible shock absorbers. The trailer can buffer fore/aft movement of the trailer.
