1. A blow-molded plastic structure constructed using a blow-molding process, the blow-molded plastic structure comprising:
a panel including an upper surface, a lower surface, and a hollow interior portion disposed between the upper surface and the lower surface of the panel, the upper surface, the lower surface, and the hollow interior portion being integrally formed as part of a unitary, one-piece structure;
an outwardly extending lip, the outwardly extending lip including an outer surface and an inner surface;
a first blow point receiving portion at least partially disposed in the inner surface of the lip, the first blow point receiving portion sized and configured to receive a blow pin during a blow-molding process;
a second blow point receiving portion at least partially disposed in the inner surface of the lip, the second blow point receiving portion sized and configured to receive a blow pin during the blow-molding process; and
a continuous tack-off at least partially disposed between the panel and the lip, the continuous tack-off extending between the first blow point receiving portion and the second blow point receiving portion.
