bmwdriver2019,
Reread dodge guy's post. He said his rig had all the added suspension bells and whistles when they bought it and it was still a handful. What fixed it was an PROPER alignment.
I like Nv Guy's analogy, too, and pianotuna's comment seems to be applicable for many rigs, especially gassers.
I just don't see how you can blame Ford when the vehicle owner does not verify that the alignment is correct per specs. Ford builds the chassis, but has no idea how much weight the coach builder is going to put on it, which can affect the alignment of the complete coach.
Weigh it fully loaded ready to travel, get front and rear axle weights, based upon these check tire pressures per the tire manufacturer and bring it to a good shop and have it aligned. Then and only then should you consider other "fixes", if needed.
That seems to be the overwhelming advice you've been given so far. Why not give it a shot? :)
