Abstract: A potential parking area level indicator is provided that includes a centralized hub with a plurality of arms depending therefrom. Preferably, four arms are provided that are spaced 90 degrees from each other thereby defining two sets of opposing arms. In operation, a driver of an RV would locate the level indicator on a potential parking area thereby placing the arms onto the potential parking surface. If the line defined by a pair of opposed arms is placed on a generally level area, indicator lights will illuminate indicating that fact. If, however, the line defined by opposing arms is placed on a grade that is not acceptable for parking, the indicator lights will not illuminate showing that the potential parking area is unsafe for parking. Proper illumination of the lights is driven by accelerometers incorporated into the arms of the level indicator.

Abstract: An improved auxiliary braking apparatus adapted for use with a towed vehicle is provided. In order to provide a more accurate device that is substantially unaffected by gravitational changes experienced while in transit, the auxiliary braking apparatus uses a solid state inertia device to sense changes in inertia attributable to the braking of the towing vehicle. The braking apparatus includes a molded reservoir/pressure vessel with integral attaching features. The reservoir may be constructed from a two step injection molding process thereby lowering overall manufacturing costs of the braking apparatus as well as improving the ability of the reservoir to be directly mounted to the housing of the braking apparatus.
