Manifold system

A trailer/dolly vehicle manifold system, comprising:

• a manifold body having a top surface, a bottom surface, a first side surface, and a second side surface, said manifold body having a longitudinal length defined by a first end and a second end;
• a groove positioned in either the top or bottom surface of said manifold body and extending along at least a portion of the longitudinal length of said manifold body;
• at least one mounting hole extending through the first side surface of said manifold body and through the groove such that said at least one mounting hole extends substantially perpendicular to the longitudinal axis of the manifold body;
• a plurality of connection fittings including at least one connection fitting located on each of the first and second side surfaces and the top surface of said manifold body and no connection fittings are positioned on the first or second ends or the bottom surface of the manifold body;
• at least one internal passageway within said manifold body fluidly connecting at least two of said plurality of connection fittings;
• at least one fastening element removably engaged within said at least one mounting hole;
• and
• wherein said manifold body is adapted to slideably engage with a module panel having an edge, the edge adapted to engage with the groove along a length of said manifold body and the at least one fastening element detachably fastens said manifold body to the module panel.
