QUICKSILVER's extremely durable all-aluminum and composite construction features absolutely NO WOOD whatsoever! Modeled after the lightweight aluminum structure made popular in the aeorospace industry, the QUICKSILVER features lightweight aluminum construction throughout, including the tongue-and-groove aluminum flooring. So, unlike traditional tent campers that are fully constructed of plywood and pine - which can rot out in just a few short camping seasons, the QUICKSILVER is made to stand the test of time!
