Hi Rick,

Tri-axle trailers will apply reverse torque (severe upward weight) to the hitching on uneven ground surface.

I'm not talking about ruff terrian road surface but a gently rolling road surface that causes the tri-axle suspension to become loaded.

When I first bought my tri-axle, I used a 5/16" ball with a 3/16" chain to move the empty trailer onto my shop pad to install my pintel hitch. I snapped that 3/16" chain and put the first ding into my new F350.

So I did another experiment. I used a 1/4" chain again on the 5/16" ball with 3800lbs load weight on the flat deck placed fully forward and I once again snapped that 1/4" chain. A 1/4" chain has approx 2600lbs breaking strength.

My conclusion: There will be a no load weight "sweet" spot on the flat deck on a tri-axle trailer, like there is with a tandum axle trailer.

If you observe the rear tire on a tri-axle while in a tight turn radius you will see the rear tire fold under the wheel center. Under the correct conditions, I could see poping the tire off the rim if one was not careful.
