Abstract: The present invention involves a window trim system with a bracket and trim ring, and a method of installing the same. The window trim system includes a clamping bracket which is press fit and screwed into preformed channels in the window frame. The clamping bracket has a receiving portion, such as a depression or catch, for interfitting with an engagement portion of the trim ring, such as a protrusion or catch. A trim ring is then snapped into place over the clamping bracket, thus hiding the screw head from sight. Advantageously, the window trim system is capable of securing the window frame to the vehicle wall with a minimal number of brackets and screws.

Abstract: The present invention involves an extension unit for a structure, such as a recreational vehicle or manufactured housing component. The recreational vehicle or manufactured housing component structure has an exterior wall, and the extension unit provides additional interior space for the structure when in a deployed position. The extension unit comprises a floor, a roof, a first wall extending between the floor and roof, a second wall operably coupled to the first wall and extending between the floor and roof, a pivotal connection linking the first wall and one of the second wall and exterior wall, and a biasing mechanism for biasing the first wall into the other of the second wall and exterior wall in the deployed condition. The pivotal connection links the first wall to the second wall, while the biasing mechanism biases an edge of the first wall into the exterior wall in both the deployed position and the retracted position.
