This results in a herky-jerky ride that is, from reports, extremely annoying. I have not felt this yet but have not been on a road that would cause it. Obviously all beds have some independent movement between the cab and bed - but the inability of the chassis to handle spaced bumps without doing the pogo pogo is a problem.
2. "Chassis Harmonic" - This is the one I feel - which is a vibration that reverberates through the chassis AFTER a single bump has been absorbed by the suspension. This, to me, feels like a shock that has lost its rebound control - though I know that is probably not the cause.

Interestingly enough, every truck I've owned or driven regularly has done both of those is varying degrees (worse in the 3/4 tons). My last personally owned truck was an '03 F150 SuperCrew, which did the same kind of things. I was able to tone it down a bit by installing some RMX Monotubes from Les Schwab. I did not expect it to go away completely, but the ride did improve.
I think a lot of the issue is that many Tundra owners just dont have a lot of experience with large trucks, particularly 3/4 ton type trucks (which the Tundra resembles a little more than the typical 1/2 ton). As a result, the reaction from the Tundra seems out-of-whack to them.
It IS a large truck, with a typical large truck frame (unlike the current F150 or Silverado). Its not going to act like a car or even an SUV in most situations. To expect it to, isnt all that reasonable. Load your truck up with cargo/trailer, and it acts exactly the way it should.
