Supports utilized to stabilize and/or support parked trailers, such as semitrailers parked at loading docks while loading and/or unloading cargo, are disclosed. Some example embodiments may include jacks mounted to repositionable frames, which may be mounted to posts. Some example embodiments may be configured to engage with king pin plates and/or king pins on the undersides of trailers.

A removable spoiler or vehicle stabilizing apparatus for a pickup truck having a truck bed is provided. The spoiler comprises a spoiler shell constructed and arranged to fit securely on the truck bed, an interior spoiler frame, at least one mounting support configured to securely support the spoiler on the truck bed, and a plurality of spoiler securement and lifting elements. The spoiler may easily be installed or removed from the truck even while the truck is hitched to a travel trailer, camper trailer or the like. The spoiler may be installed or removed with any suitable device, such as a crane, jack, jack stands, cherry picker, auto cherry picker, travel trailer tongue-mounted lift/crane, lifts, roll on/off platform or the like. The spoiler may also be used as a multipurpose device, and may provide a golf cart enclosure, and may further comprise at least one utility shelf.

The present disclosure relates to a device and a method for controlling a heater wire of a rear window of a vehicle. To reduce a drag force acting on the vehicle by pushing positively charged air (containing dust) by a positive voltage induced in the heater wire, and prevent the dust from adsorbing on the rear window of the vehicle, the device includes a switch located on a connection line between an output terminal of the heater wire mounted on the rear window of the vehicle and a negative (−) terminal of a battery disposed in the vehicle, a booster for boosting a voltage output from a positive (+) terminal of the battery and supplying the boosted voltage to an input terminal of the heater wire, and a controller that controls the switch.

A downforce system for a vehicle includes: a restrictor configured to restrict a flow of air into a region that is defined at least in part by the restrictor and a ground surface, a rim disposed on the restrictor and configured to form at least a partial seal with the ground surface; a dedicated pressure source disposed outside the restrictor and connected to the restrictor via an air flow path, the pressure source being configured to generate a pressure differential across the restrictor; and a dust and debris removal system configured to prevent dust and debris from exiting the downforce system via the air flow path. By generating a pressure differential across the restrictor, a downforce which acts on the vehicle may be generated. The downforce may result in an improved grip or traction of the vehicle, which may improve handling and safety of the vehicle.

A removable weighted vehicle safety guard system having a safety attachment that removably attaches to the back end of a vehicle to add weight, thereby helping to keep the back end of the vehicle stabilized while driving in inclement weather or on slippery road surfaces, and additionally forms a brush guard to prevent damage to the vehicle should another vehicle rear-end the user's vehicle. The removable weighted vehicle safety guard system attaches to the back end of the vehicle via the hitch and is secured using bolts or trailer pins. The removable weighted vehicle safety guard system provides static weight to the back end of the vehicle but may optionally also receive additional if needed. The additional weight may take a number of forms, including weight blocks, and can be added to the removable weighted vehicle safety guard system via bolts or trailer pins.
