Abstract
A telescoping drawbar is provided to insure a variable length connection between a pulled trailer and a tandem connected trailer supported on a portable dolly. The telescoping drawbar includes a number of telescoped tube segments which are aligned and secured with interlocking wedges, plates and mating stops located on the surfaces of overlapping telescoping sections. The wedge-shaped plates and associated stops securely interlock the telescoping sections and accurately align locking openings for insertion of locking bolts.
