Question: Why do I need a weight distribution hitch with a Trailer Toad?
Answer: There are three main components to a Trailer Toad- First, is what we call the "front crossmember". This part holds the WD front shank (L-shaped bar that slides into the receiver hitch) and basically, it never moves once it is attached to the receiver hitch but the vertical holes in the shank allow us adjustment to match different hitch heights. Second, is the main frame. This frame attaches to the front crossmember with two 3/4" bolts and these create a "hinge" that allows the main frame to travel up and down without putting stress on the front crossmember that attaches to your receiver hitch. Third, is the Dexter torsion axle that bolts to the main frame. The axle attaches with a HD 2.25" vertical spindle that is welded to the axle and bolts to the main frame via an 8-lug Dexter hub. The vertical spindle is what allows the axle to "turn and follow" the tow vehicle on corners so the tires do not scuff. This also means the main frame of the Trailer Toad is allowed to move vertically on the "hinge" so it can go through dips and over bumps without putting pressure downward or upward on the receiver hitch/tow vehicle. This is the "isolation" part of the Trailer Toad function. Because it is hinged the trailer tongue weight could make the rear of the Trailer Toad, where the ball is mounted, want to move up and down a lot and it would not be stable. The Weight Distribution hitch head and the torsion arms are mounted to the rear of the Trailer Toad and the tongue of the trailer to act as "ride height maintainers / vertical travel dampers. We do NOT use the WD hitch to do any lifting, the Trailer Toad can take the weight, we are just stabilizing it with the WD hitch head and arms to improve overall handling and control.
