If I get what your saying, would it not apply to a single-wheel with two pivot points? OP's setup has a cross-bar on a hitch receiver. Tell-tales might show torsion around the centerline. |
If I am reading you correctly (expand what was said) my concern would be how much the truck frame is flexing (due to age and miles. All frames flex, even on the 18k empty Peterbilt I drive). One way to "eliminate" that concern -- which is more about uneven or unequal flex -- is to see whether it can be seen via trailer attachment points.
A rough ride isn't always easy to fix much less diagnose.
Second, and easier, is that the trailer frame can in no way accommodate as much applied force as the truck. The OP has this in mind. It is a balancing act. The forces onto the trailer from the truck are significant. One can damage (separate) the A-frame on some highly expensive travel trailers with a too rough riding truck.
