An assembly for mounting or dismounting a vehicle comprising a step that is structured to slide on an axis longitudinally along the vehicle on a rail. The step has a pivot assembly enabling rotation from a stowed position to open position and back. The slidable step can be stowed in place by engaging a latch mounted to the vehicle. A handrail assembly can be inserted into a handrail-receiving member to facilitate grasping a handrail upon mounting or dismounting the vehicle.

Systems and methods for subsurface secondary and/or tertiary oil recovery optimization based on either a short term, medium term or long term optimization analysis of selected zones, wells, patterns/clusters and/or fields.

A modular side rail and removable step system for a vehicle is disclosed. In one aspect, the kit includes first, second, and third removable steps that may be mounted to the side rail. In one aspect, the side rail main body has a channel-shape defining a longitudinal opening between an adjacent first side and an adjacent second side. A plurality of step attachment arrangements may be provided on the first side of the side rail main body to allow the first, second, and third steps to be mounted to the side rail main body in various configurations. For example the plurality of step attachment arrangements may be arranged and configured to provide attachment locations for mounting the first and third removable steps in a first step assembly configuration and for mounting the second removable step in a second step assembly configuration.

A portable ladder having a pair of elongate stiles spaced from one another and each having first and second ends, and extending in a first direction; and a plurality of rungs each extending between the elongate stiles transverse to the first direction and having opposed ends one of each attached to each of the elongate stiles and each of the plurality of rungs being spaced from one another along the first direction, the rungs being arcuate in shape between the opposed ends.

A vehicle is provided with an integrated and removable traction device, such as a tread board. The traction device may be integrated into a bumper of the vehicle. When mounted/installed on the bumper, the traction device can act as a cover to a storage unit implemented in the bumper. When removed, the traction device can be placed under a wheel of the vehicle to provide increased traction on certain surfaces. By integrating the traction device into the vehicle's bumper area, the traction device need not occupy, e.g., interior storage space of the vehicle.

A vehicle includes a vehicle body, a vehicle roof rack component and a vehicle ladder. The vehicle body has a roof body part and a side body part. The side body part defines a wheel well of the vehicle. The vehicle roof rack component is installed to the roof body part. The ladder is detachably installed to the vehicle body. The ladder extends from the roof body part and over the side body part to the wheel well.

A pet ramp system has a central pier and at least one ramp with an axle that is received in at least one axle receiver disposed near the top of the pier. The pier's axle receiver(s) permit installation of the ramp axle when the ramp is oriented at less than a predetermined angle from vertical, but the axle receiver(s) will not permit separation of the ramp from the pier when the ramp is lowered to any of a plurality of use positions that each are at more than the predetermined angle.
