Abstract: A securing mechanism for use with a recreational vehicle (RV) slide out assembly. The securing mechanism structurally interconnects the slide out assembly to the RV when the slide out assembly is in a retracted position and when it is in an extended position. Specifically, loads in the RV induced from the road, from passengers, from equipment, and other various sources are distributed through the slide out assembly. Advantageously, flexure of the RV walls around the slide out opening is reduced. As a result, walls and their fixtures are less likely to be damaged due to flexure, seals between the RV walls and the slide out are more likely to stay intact, and the size of slide outs can be increased without compromising the structural integrity of the RV.

Abstract: Recreational Vehicle (RV) are usually a trailer or a bus size vehicle used for camping or traveling, that is fully self contained, and contains all the amenities like a home, such as kitchen, bedroom, bathroom, shower, and living room etc. However due to DMV restrictions, those vehicles can't be wider than a certain size, usually 8 feet. Another reason for the width limitation is for the safety of the transporter(s) and traffic. If the vehicle is too wide it makes it unsafe and hard to maneuver. That is the reason coach and RV manufacturers try to produce an 8 feet wide RV that expands, so the extra space when parked gives more living area. The invention hereof offers an alternative way to double the available living space by having a floor plan feature counter-double slide out which enable us to provide a more spacious and free flowing transportable dwelling unit, which maximizes the consumers ability to have the extras that the conventional Slide-out arrangement doesn't offer.
