Abstract

See full text

Disclosed is a trailer leveling support, comprising a plurality of wedge shaped pads for supporting a trailer parked on an angled surface. The upper portion of the wedge is provided in a flat configuration to allow placement of any trailer accessory, while the base surface is provided at an angle with respect to the upper surface, allowing the base to rest against an angled support surface while the upper surface is positioned in a level configuration. The pads may be stacked to achieve the desired angle based on the trailer support surface. The device also includes a strap for securing the pads together, or to the trailer for added stability. The footprint of the device occupies a sufficient surface area to distribute the weight of the trailer over a larger area to prevent the trailer tongue from sinking into a soft surface.
