ABSTRACT:
A flatbed trailer includes first, second and third flatbed sections whereby the first and second sections are joinable in an extendable configuration and the first and third sections are joinable in an alternate and typically standard configuration. The trailer can be switched between the extendable and alternate configuration within a fairly short time. The invention thus eliminates the need for both a standard extendable trailer and a separate non-extendable trailer, and provides the ability to use the alternate configuration when the extendable configuration is not necessary in order to substantially reduce the weight which would otherwise be involved with the use of the extendable configuration.
