Here’s just one visual. See for yourself.

All structures have a natural resonant frequency. That series of bumps was clearly very close to the torsional resonant frequency of the Toyota's chassis. BUT ... Select a different resonant frequency - a different speed through the bumps - one that matches whatever the resonant frequency is of the other trucks! - and they'll do that, too, but since that new resonant frequency will no longer match the Toyota's resonant frequency, the Toyota won't. Six of one, half dozen of the other.
Having said that, it's recognized that the ride quality of a vehicle will be best if that natural frequency is above what is normally seen on the roadway, so that the oscillation doesn't occur during normal driving conditions or anything resembling that. This leads to the common and unsurprising conclusion that a torsionally stiff chassis is "better" for ride quality. And what's the best way to get a torsionally stiff chassis? A
unibody rather than a separate frame and body!
The Honda would likely do best in that test ... and the all-independent suspension would probably follow the bumps better. But that does NOT imply that it's the best truck, only that it would likely do better in that particular test.
Trucks, historically, have been DESIGNED to have a certain amount of torsional flexibility in the chassis ... the torsional flex was essentially part of the suspension.
If ride quality and freedom from NVH is a major criteria in your truck selection then your choices are the Honda (unibody, independent suspension, rides and handles like a car) or the Dodge (coil spring rear axle with a linkage rather than leaf springs). The Ford's positioning of the shocks outboard of the frame is a better design but it doesn't solve the pretty much inherent roughness of leaf springs.
Friend of mine has a current-body-style Dodge pickup with the coil spring rear end and it rides very well.
I am somewhat looking at getting a bike hauler for next year but I am holding out to see what the upcoming Ram ProMaster van (a.k.a. European Fiat Ducato) is like. Front wheel drive (means a lower loading floor than any other van - or any pickup), 4 cylinder diesel engine, ginormous interior (like Sprinter). The also-upcoming Ford Transit might be another option but it's still rear drive, and the program keeps getting delayed - I have customers that will be building parts for those, so I keep hearing stuff like this.
