Question:

Just bought used 18k demco autoslide. Turntable is slightly to the left. How to straighten would be the question. Waiting on part 6401. Math says mount on lowest setting, does this seem right?

You would need to reach out to Demco directly to straighten out the mechanics of the hitch and confirm that it's still safe to use. The correct way to measure for hitch height would be to:

1. Level the trailer and measure from the ground to the king pin plate (A).
2. Measure from the ground to the bed of the truck (B).
3. Subtract measurement (B) from measurement (A).

This measurement would be where the height of your Demco Autoslide 5th Wheel Hitch w/ Slider # DM8550024 would need to be set at.
