The draw keeps you in balance when the trailer is towing and helping to maintain their body weight on the tow bar required for towing control.
It also adds rigidity to the chassis and will assist in keeping the trailer correct and stable based on an axle and load placement.
A drawbar should have the power vertical and a good side and depend on the size of your trailer and your willingness to take him. It will determine the size and design of the materials required for use.
The drawbar does a lot of work while towing. If the trailer is built with an undescribed drawbar or the trailer is continuously overloaded or unbalanced, this repeated loading and unloading (cycling) of the tension on the drawbar. The drawbar can create subtle cracks within the grain structure of the drawbar material.
