Abstract: A receiver hitch step attachment mounts to the existing receiver hitch of a pickup truck and supports a set of steps that are adjustable laterally and vertically. An auxiliary stabilizer leg is provided for engaging the ground beneath the attachment when the truck is parked in order to support the vehicle against rocking when weight is applied to the steps or when moving about in the camper.

Abstract: An improved apparatus for projecting a viscous coating material onto a surface whereby a constant pressure pump propels a viscous coating material, such as tar, pitch, oil or the like, through a high-pressure relief valve to a spray gun or wand. The rapid flow of the material through the restricted orifice of the relief valve produces sufficient friction to heat the viscous material thereby reducing the viscosity and rendering it easier to apply. A secondary relief valve is provided to reduce any excess pressure that develops and to recirculate any unused material to a supply resevoir.
