A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

A vehicle corner module (VCM) is provided for regulating motion of a host vehicle which comprises a vehicle-onboard vehicle-controller. The VCM comprises a sub-frame mountable to a reference frame of the host vehicle; a wheel-hub assembly comprising a wheel-hub; VCM-sub-systems mediating between the sub-frame and the wheel-hub assembly, e.g., a drive subsystem, a steering subsystem, a suspension subsystem and/or a braking subsystem; and an VCM-onboard VCM-controller, comprising one or more processors and a computer-readable medium storing program instructions that, when executed by the one or more processors, cause the one or more processors to establish a communication link with a vehicle-controller, including electronically transferring information about the VCM from the VCM-controller to the vehicle-controller, and to perform, in response to an installation of the VCM on a vehicle, a post-installation validation-process that includes validating the VCM-subsystems and communicating a result of the validating to the vehicle-controller.

A refueling vehicle may have a front fuel dispensing module with at least one or more hoses for dispensing fuel product from the fuel tank to an external tank. The front fuel dispensing module is located between the cab and the fuel tank containing the fuel product.

A truck or tractor vehicle includes a frame having a longitudinal centerline, an operator cab mounted relative to the frame via a cab suspension, the cab having a longitudinal centerline, the cab suspension comprising a front suspension and a rear suspension, the rear suspension comprising an adjustable panhard bar attached at a first end to the cab and attached at a second end to the frame, the adjustable panhard bar being adjustable in length to position the longitudinal centerline of the cab at a desired angle relative to the longitudinal centerline of the frame.
