Trailer construction

A trailer including an elongated chassis having front and rear ends and sides. means for towing the trailer attached to the front end of said chassis so as to extend therefrom, undercarriage means including wheels attached to said chassis between the ends thereof, said undercarriage means including wheels for supporting said trailer extending beneath said chassis and a trailer body having an internal floor mounted on said chassis so as to extend upwardly therefrom, said body extending from the front to the rear of said chassis and having sides corresponding to the sides of said chassis in which the improvement comprises:

• a series of spaced, parallel joist means mounted on said chassis, said floor being supported by said joist means and being spaced from said chassis by said joist means, said floor being continuous and flat between the sides and ends of said body,
• all of said joist means extending transverse to the length of said chassis,
• all of said joist means except those adjacent to said undercarriage means extending between the sides of said body,
• said undercarriage means being constructed so that said wheels extend generally upwardly from said chassis means adjacent to the sides of said body,
• those of said joist means adjacent to said undercarriage means terminating within the sides of said body so as to provide spaces located generally above said undercarriage means for said wheels at the sides of said body, and
• tank means for holding fluids associated with the use of said trailer located between those joist means generally above said undercarriage means.
