## Cross-Memberless

## Steel Construction

Is overall weight a concern for your haul? Cross-memberless steel results in a lightweight design, and smooth sidewalls allow for easy maintenance. Truck bodies made from cross-memberless steel are also available with pronounced sidewalls if your application calls for more strength and durability.
