I hear where your coming from though but look at it from my perspective if you will. You keep saying that I should have bought a Silverado, Ram, F150 1/2 Ton Pickup. Thats exactly what I thought I was buying from Toyota.. a 1/2 Ton Pickup with the expectation it would ride and handle like every other 1/2 ton pickup.. How did i know it was really a 3/4 ton and would have the characteristics of a 3/4 ton pickup? They never told me and the other reason I went with Toyota was their quality and reputation.
Its all cool man, nothing wrong with a good debate!
I really dont ever recall Toyota advertising claiming it rode like the other current 1/2 tons, so any expectation of such is precarious at best (they did advertise the hell out of its towing and hauling abilities though). I personally never had that expectation, and nothing Toyota ever did/said ever lead me to assume that, let alone expect it.
The current domestics 1/2 tons really have gone the way of the car-like attributes, but you dont have to go back too far when they were being made like trucks, look at the pre-2002 F150 or Silverado's. My Dads '98 F150 doesnt ride much different than my Tundra as far as bounce and frame reverb.
We can agree to disagree, but we're all still friends here I hope!
This is the smoothest truck i have ever driven, until you hit the f'ed up so cal freeways. It is only certain parts, that's why I did not notice it on the test drive. I did test it on the fwy, for about ten miles, but it was a goods part of the fwy(one of the few) and it rode like a caddy.
When it starts to bounce, it very much feels like a 3/4 or 1 ton. Put a few hundred lbs of camping gear or a trailer and it is a sweet ride. Good thing I don't usually hit the so cal fwys empty. The 06 GM stuff I drive at work, (1/2 ,3/4 ,3/4Hd) when they start reacting to the so cal pavement you feel it in the front, sometimes it is so bad that your foot and leg dtart moving on the throttle and it feels like the trucks are surging. Thanks, CALTRANS.
bilztrd, X2..........most people on here don't even know they have the bed bounce because they're not here in So Cal to feel it on our freeways, I've driven mine to Bishop and Vegas and no problems out those ways once you get off the So Cal freeways it's nice and smooth.
My 01 Silverado ext cab Z71 4x4, virtually identical wheelbase as my 07 Tundra DC TRD 4x4, rode great (but not car smooth) on the same So Cal freeways. Yes I like my Tundra, but Toyota blew it on the ride on rough roads.

I feel really badly for those in Southern CA and agree I don't think most understand what is meant by "Bed Bounce." I have driven my Tundra from the top of North Carolina to Connecticut and never felt "Bed Bounce." I remember reading about it and seeing my bed bounce a little on the highway here and was like, "who cares.....I don't get what all the fuss is about."
Fast forward a few months and I'm driving my Tundra down one of the "5s" in LA and rear of the truck starts to bounce. I pull over thinking one of my wheels has come loose so I checked them and a few other items and found nothing (I felt this could be possible as I had driven across the country 3500 miles towing 7000 lbs). Head down the highway and sure enough it starts bouncing again to the point where I really feel like something is wrong. If you speed up or slow down the problem goes away. Loaded up and pulling a trailer the problem doesn't exist.
I think the term "bed bounce" is fooling people because I bet the bed itself has nothing to do with it. If the bed was removed I guarantee it would do the same thing. It has to be a resonant frequency that occurs based on the concrete slab lengths in CA that at a specific speed cause enough harmonics to flex the chassis to the point where it feels like the rear wheels are bouncing off the ground and my a&! is bouncing off the seat .
If I had to drive my Tundra every day in LA I would have sold it! Thank God I don't because I love this truck but that's how unbearable it would be to drive on LA freeways.
To say the gm truck did better than the Tundra on the u tube video is really just crap the damn wheels were not even making contact with the road how is no control better? The Tundra could have went around a curve or stoped because the tires were still in contact. I agree the Tundras not the best riding truck and does have some bed bounce issues but as far as a 1/2 ton pickup goes it tows the best which is what they played over and over in the commercials maybe you should have bought a taco or an suv? Your tax dollars are obviously getting spent poorly if the cannot even keep the roads decent maybe you should go after goverment corruption so you can have some decent roads? In saying all of this I have experienced slight bed bounce and I can feel the reverberation when going over a speed bump slightly fast but it is still the most "truck" of all the 1/2 ton trucks out there. I have drove a new silverado and it just seems thin compared to the Tundra. The ford is a decent truck but with no powertrain to back up it's supposed strength it may be able to tow 10k but it would work the crap out of the 5.4 going up a steep mountain grade. I have also been behind the bed bounce free ford f150 on the highway that the bed was bouncing and my Tundra was not if I would have had the camera that day I would have shot video of it and slapped it on you tube. If they had done the test a different speeds the outcome would have been different why would they only show the test at one speed and not others? It's because they new the frequencies that were most harmful to the other trucks and the least harmful to theirs.

There is a cure. Install airbags - firestone ones. I did and all bed bounce and shake is gone. Period. I have a very plush quiet ride now, plus the truck now corners flat like it has a sway bar. You can purchase them on ebay for around 200. I installed mine in 4 hours with simple tools. You'll be happier with your truck's improved ride and handling, even if you don't have bed bounce!
Thanks for providing the info below.. I sent you a PM as well. As much as I appreciate folks recommending solutions to the bedbounce.. I just wanted to point out a direct conflict of information regarding the use of Airbags to solve the bedbounce issue.
The last 2 pages are of most interest where several members stated the airbags did not help with the bed bounce.. I believe you posted in that thread above too.
This certainly makes things difficult.. One person saying yes and other saying No.. which is it? Then factor in each person's experience with bed bounce is subjective at most.. So what cures it for one might not cure it for another.. Round and round we go!. '

The linked thread also describes how air bags reduce articulation off-road, so the minority of us who are hard core off-roaders probably wouldn't like the air bag solution.

It holds water, and probably other 'stuff' just fine
Its fairly clear to me that Toyota made the new Tundra specifically to do truck-duty things, and do them as best as can be done. Its clearly aimed at the people who need a truck that does truck-duty thing well. It wasnt really intended for people who want a truck, but do mostly car-like things with it - that was definitely not their target buyer.
Now take the new Ram, F150, or even Silverado, those trucks have been made much more car-like. All those 1/2 tons have steadily gone away from being truck-duty trucks, to car-duty trucks. Yup, they ride smoother, maybe handle better, more like a car, and they do those things well. Those are definitely aimed at the target buyers who do mostly car-like duty with their trucks. None of those 1/2 tons can really hold a candle to the new Tundra when it comes to truck-duty stuff, hauling loads or towing big stuff.
So the new Tundra definitely meets the needs of the audience it was really intended for. Just as the other 1/2 tons meets the needs of their intended audience.
By some of the reactions noted in this topic, its clear the Tundra doesnt meets the needs of those people. They dont want the harsher characteristics which is totally typical of larger trucks. They bought the wrong truck, probably should have gone with one of the other 1/2 tons. The new Ram would probably be a good choice, its a lot more car-like than truck these days.
Toyota is right on when they say theres nothing to fix. Its a truck, a real truck, and it acts just like one should.
The Tundra has neither high(er) payloads or any other attributes that make it more "truck" like. And its towing numbers are very close, if not less, than some 1/2 ton GM's depending on gearing etc...
As far as handling, depending on what published tests we read, it is either slightly faster or slightly slower through slaloms and is at or near the top regarding skid pad numbers.
In fact, given the tailgate issues and the rather thin wheel wells in the bed, I'd say it was geared LESS for actual "work". (my fat arse has NOT dented the wheel wells but they certainly do flex more than my Ford's)
I do believe the Tundra to be a tad over-sprung and over damped in the rear.
A WAG on my part is the reason Toy refuses to "fix" the problem is they'd probably have to change GVW's if they start messing with the rates....
As far as actual "flex", I call BS on that too. I've driven too many trucks that exhibit the resonance...including my current F-250. If it was "flex", I would think there would be some sign of metal fatigue....minute buckle marks??....to full on loosening of components.
And if I'm wrong about it flexing, the bottom line is, is it's the suspension being too stiff that's allowing it.

I doubt there is any flexing going on. It is all happening in the springs and suspension. It is very much like double bouncing someone on a trampoline. Something about the spring rate's resonant frequency is directly in sync with the spacing of the concrete expansion joints on the freeways. Instead of absorbing the variations in the road, the springs begin to accelerate in perfect rhythym with the length of the slabs and launch the back end of the truck up. Again, like a double bounce on a trampoline, my guess is the springs absorb the first bump and as they recover and extend back down, it is exactly the same time the dip is there to allow them to overtravel. They spring up just as the hill is there and then extend back into the next dip. This starts to launch the back of the truck up and down in the air and keeps getting worse and worse until it is accelerating the back end of the truck up in the air pretty good. The bed isn't boucing.. the whole back end of the freakin truck is bouncing. There is very likely NO frame flexing going on or it would absorb some of the bounce in the springs. TOYOTA SHOULD HAVE CAUGHT THIS and they are liars if they say the spring rates can't be modified to eliminate it. Maybe they could, but you would loose payload and towing capacity or it would require them to actually spend a boatload of money to replace all the springs.
Do you want to see what resonant frequencies and harmonics can do in the extreme? The wind gusts start to accelerate this structure up and down until it fails. Check out the video below...

Toyota should have caught this and the spring rates should be able to be modified so that they don't accelerate the vehicle up and down in the bumps and dips.

Does anyone find it strange that this was the TACOMA bridge??? Maybe it should have been the TUNDRA bridge...
To add to that, the resonance is directly affected by speed.........I can speed up to 90+- on those stretches (of course, only when the road is closed to the public) and the truck smooths out.
There was a reason Ford chose 28MPH for THEIR video.....and don't be fooled, that was a Ford produced video.

You cant cite the manufacturers numbers, but the simple fact is that it tows and hauls better than all the other current half tons. The suspension, engine/tranny, brakes, etc, put the others to shame.

Perhaps, but the other 1/2 tons have a more car-like feel when driving. Most of the current reviews reflect that. That also doesnt delve into the actual "ride". The other current 1/2 tons are made to have a more car-like ride, and less truck-like.

The body panels might be thinner, etc, I've noticed that too. But when "doing the job" of hauling/towing, it excels, and thats undeniable.

Kinda what makes it good at pulling so much weight so well.

Its stiff alright... put a load in the bed, like trucks are supposed to be used for, it'll ride great!

There were a few features that I thought the Tundra had over the comp. (there's a few that Toy dropped the ball on) but I agree that the drivetrain was probably the biggest selling point for me.
We've had a 2 year free ride, but now that GM is making their top drivetrain available across the board (6.2l/6 speed) and Dodge is stepping up, we now have the oldest truck in the mix!!!
I can't wait to see PUTCO's 1/2 ton test results.

I'll have to dig those reviews up......for some reason, I seem to remember them touting the Tundra's smooooth ride and quietness. On a purely subjective note, except for the occasional concrete freeway, I think the Tundra is as smooth and car like as any 1/2 ton I've driven.

That's a tough one......it certainly pulls better than any current 1/2 ton, but I attribute that to the powertrain. As far as hauling goes, thanks to the WWW, I am very careful on how I use my tailgate and try not to let things slide around in the bed; I've never had to give that a 2nd thought with my trucks in the past.

Debatable. Except for the power difference, do our trucks really tow any better than the comp???

Just my theory on why they resonate over some conditions.
I love my truck and thought it the best 1/2 ton at the time I bought it.
We'll just agree to disagree that it's some kind of uber work truck.
HOWEVER, I feel the same way concerning all the 1/2 tons.
Truth be told, if I wanted a 1/2 ton to beat, I'd probably get a base F-150.
