I've thought about trying these or a version of them. Did you do front and back or just front? I would think in a longer trailer you might need to do both just from tire squish at the pivot point. I've also thought about another set of jacks near the center to take susupension/tire bounce out of the equation.
Just the front.
The tires being the center of rotation, adding a jack in this location is counter intuitive. (it will make matters worse)
The 4x4 and chain rig does the very same thing, but supports the tongue directly vs the jacks. Its a bit red-neck, but that type of support system will have the same good result.
IMO, those who still see and feel suspension and tire movement on jacks are not watching the watching the jacks, and how they allow the flex and movement to occur. Stabilize the jacks (at the outermost corners of the trailer) with additional support, and all movement disappears.
Picture lifts and even fire trucks with stabilizing systems. Its the jacks that must do all the work...and at the extents of the vehicle. (Not near the center.)
