The slide-out room is constructed from monocoque laminate wall panels interconnected by an end wall sub-frame. The end wall sub-frame is constructed from unique main extrusion members that are interconnected using key-locked miter joints. Each main extrusion member has a generally Z-shaped cross section, which allows the members to be joined using two joint keys fitted into spaced parallel key channels formed in the main extrusion members. The end wall sub frame also includes secondary extrusion members welded to the main extrusion members and interconnected using a lap joint. The secondary extrusion members have legs that are spaced from the legs of the main extrusion so that the monocoque panels can be fitted and secured between the legs to and from the side walls, ceiling and floor of the slide-out room. A monocoque panel is bonded directly to the outside of the end wall sub-frame to form the slide-out room end wall.

A woodworking jig is used to set cutter height and horizontal fence position when forming lock miter joints with a forty-five degree (45°) lock miter cutter on a router table or shaper. Vertical and horizontal reference lines are formed on the exterior surface of the jig. Setup is accomplished by adjusting the cutter height and fence position until the appropriate reference lines on the jig align with centerlines or centerline-derived lines on the edge of the stock. Using the appropriate reference lines, the jig is used to complete setups for standard lock miter joints with boards of equal thickness, non-standard lock miters joints with boards of different thicknesses, and offset lock miter joints. The jig has no moving parts, requires no calibration or measuring devices, and works with any lock miter router bit and most shaper cutters. The jig locates the geometric center of the router bit profile with precision.
