This option allows for the adjustment of the length of the machine's cargo compartment using an extendable telescope mounted in the frame. Additionally, included with the telescope, trailers with this option are equipped with a folding lighting beam instead of a standard fixed beam.
This option is available in models 71, 81, 842, 942, and 1042. In FAO FAR forestry trailers of 1142 and larger, the extendable telescope frame and folding lighting are standard features.
