Abstract: The invention refers to a drilling tool and method that, among other aspects, provides for a sleeve with expansible pads for positioning the drilling tool in the desired direction during drilling. The pads are hydraulically expanded and retracted by a valve system which selectively diverts mud flowing through the tool to the desired pads. The tool may also be provided with a flexible tube connecting the sleeve to drilling tool for maneuvering along deviations or curves in the wellbore.

Abstract: A bed for a pickup truck having side gates in the sidewalls thereof and a tailgate in the rear wall thereof having exterior contours identical to the exterior contours of the wall within which the gates are located, to provide increased accessibility to the interior of the bed and an aesthetically appealing design. The gates are supported to provide strength to resist against loads disposed in the bed that may be forced against the gate by having support members secured thereto on the inboard side of the gate along with the gate having a strength contour along its inboard side. The bed also has a low profile yet having support for heavy loads by having the floor joists separated, having inboard joists secured to the chassis of the vehicle and outboard joists secured to the bed below the floor of the bed.
