I feel it has two different types of vibrations, one that occurs over low speed rough roads and sounds like it's from the front end and the other over large sharp differences in pavement like high expansion joints, from the rear end (axle hop)
I changed my shocks 4 times at my expense and ended up with Koni Raid shocks from Europe to tame the beast. Also installed Michelin MS2s for winter and Michelin LAtitudes for summer. It's better but not fixed.
IMO there is something ingherent with the chassis dynamics that I know I feel, but others (even in my truck) don't feel. I have an overly sensitive buttometer, and I'm accutely aware of the difference between what should and shouldn't be there.
Same as other posted I too have BMWs, Merecedes, older 100 LAnd Cruisers and these are all much more isolated. I think the 200 got too close to the Tunda and took on some pickup truck like characteristics. I read about bad body mounts in the Tundra and I'm going to investigate this further with a gopro camera.
Love to hear about other opinions as I have exhasted IH8MUD. They think I'm nuts (as does my dealer)
