>>The brakes on a 3/4 ton pickup are substantially larger and more powerful than those on a 1/2 ton.

Apparently not when it comes to the Tundra. Here's a comparison:

2500HD Siverado

Front Brake Rotor Diam(in): 12.8
Rear Brake Rotor Diam(in): 13

F-250/350

Front (rotor diameter) 13.66"
Rear (rotor diameter) 13.39"

Toyota Tundra 1/2 TON truck:

Front Brake Rotor Diam (in): 13.9
Rear Brake Rotor Diam (in): 13.6

Wouldn't the suspension play a roll in stopping and front brake wear?

I'll stick with the Hd trucks.

When I come down the mountain passes (Cascades) I "shift" my automatic 6-speed tranny on my Tundra from "D" to "4th" or which ever gear the computer in the tranny decides is best. I only have to tap the breaks every few minutes like when somebody cuts in front of me. For the most part it will hold the at about 55-60 mph. The 2012 f250 (and I'm sure other rigs) have this tranny feature available too. The tranny temp gauge doesn't change a bit.

Mister, you must have had a problem with tranny or trailer brakes. Glad you made it to the bottom.

I can't speak for Consumer Reports or JD Power, nor have I read their ratings report. My own experience is as follows:

02 Tundra Ltd with the 4.6l gas engine:
- 75000 miles over 7 years,
- regular maintenance and $300 for failed O2 Sensors,
- failed rear universal joint replaced under warranty.

09 Ford F150 Platinum with 5.4l gas engine:
- 40000 miles over 3 years (still under basic warranty),
- regular maintenance and,
- towed in to dealer after driveshaft failure,
- transmission "brain" failure (the PCM and solenoid valves they told me) and barely made it to the dealer in "limp home mode",
- manifold exhaust bolt failure requiring replacement.

Looking at a new vehicle, I can buy the 100,000 mile 7 year extended warranty for $2600 with a Toyota. The same warranty on a new Ford is $4300. Conclude what you want but I suspect the warranty price is heavily influenced by unbiased probability of payout based on statistics.

So, you might ask why did I buy the Ford? It is a beautiful truck, comfortable, rides excellent, and has a very sophisticated tow management system. It was also $9000 less than the comparable Toyota, at the time. When I bought the F150 in 09 there was no Airstream and no trailer of any kind in the mix, although I thought there might be in the future. I was very much predisposed to buy another Tundra, but I was not impressed with the new Tundra. My old one was built in Japan and although many interior parts were more car-like than rough-and-tumble, as a truck it was the little engine that could. The new Tundra by comparison seemed big, ungainly, and unfinished. I opted for the Ford, with it's beautiful interior and hands free SYNC system. Seduced by the dark side probably.

I have not towed much, as the AS will see its first anniversary this coming June. What I can say to date is that in my situation with two adults, two children, one dog and the incredible number of things that get brought along for this gang my 1/2 ton is at or over it's payload limit. I need to reduce the tonnage or get a bigger truck. This is just my situation. I met a couple from Texas this past summer who were full-timing with an identical AS towed by a late model Tundra. Just the two of them and one cat. He has been all over North America and was quite comfortable with his 1/2 ton.

It would be presumptuous for one "newbie" to offer another advice, especially on the choice of tow vehicle. The comments in this thread that speak to determining your needs make sense to me. I plan to stay the course for one more summer, which is about 1500 miles of towing on relatively flat roads. I will pack smarter and pack less, and I will buy a new tow vehicle in 12 months for the 2013 season. Maybe by then someone will make a super reliable 5/8 ton gas diesel electric supercharged hybrid, hopefully in white.

Don

Not sure where you got your info, but it is wrong.
For 2012,

Silverado 2500

Front rotor: 13.8 X" 1.57"
Rear Rotor: 14.7" X 1.34"

Tundra:

Front Rotor: 13.9" X 1.26"
Rear Rotor: 13.6" X 0.71"

Didn't look up Ford. With rotors and heat it is all about mass and ventilation. Toyota 1/2 ton has SUBSTANTIALLY less mass than a 2500 Chevy.

HOWEVER, it is kind of a silly comparison to begin with. If you need a 3/4 ton, I wouldn't advise substituting a 1/2 ton any brand. They are not nor ever will be made for the same duty cycle.

Edit: I looked up F250 and I couldn't believe my eyes....but on three separate websites (Ford website does not provide thickness spec) this is what I found:

Front Rotor: 13.66" X 0.5"
Rear Rotor: 13.39" X 0.3"

Can that be true???????

F250 diesel 6.4l model years 2008-2010 just an FYI.. I have a 2010 F250 for towing my Sport 22 FB (complete overkill) and my 27' boat (tandem axle). We are upgrading to a 30' Flying Cloud (ordered!).

Mileage going downhill with a tailwind on a sunny day is 16. If I'm towing the boat, about 8-9, and the Airstream allows me about 11mpg. Keep in mind this is a diesel... Mileage is no better than with my prior gas F250, although admittedly the gas engine was significantly underpowered. The poor mileage on the diesel is due to emissions controls, specificaly the diesel particulate filter.

The F250 will tow anything and seems to be bored with anything less than 7,000 lbs. The ride is also wonderful, but I have not been in a Tundra. The 2011-2012 model year for F250 uses a direct injection urea system rather than DPF and provides an increase in mileage of 2-4 mpg.

Good luck!

DPF and DEF (urea injection) are two separate things. The DPF is still in the Ford as well as GM. It captures soot and burns it off when it gets full.

DEF is injected into the exhaust stream to control gasses (NOx) in the exhaust. I believe you'll still find both on 11s and 12s.

No. Ford lists minimum front brake rotor thickness as 1.44" (you cannot machine them thinner than this); rear is 1.1. This is on 2005 F250 Superduty; I don't have newer specs.

Yeah, even if they were solid rotors, that would be THINNNNN!!!!
But I sure can't find an online reference to thickness. Maybe someone has a 2012 service manual?

You are correct... My mistake. The 2008-2010 F250 models are known for poor mileage, and I should have stopped there due to my lack of technical knowledge. With higher fuel prices on diesel and mileage that's no better than a gasser, I would rethink my decision to go with a much more expensive diesel engine. I might still make the same decision based on my towing needs, but I doubt it. In Michigan, I have a concern that the winter road salt will ruin the body before I get full use out of the engine.

FYI the Tundra with the TRD package has a stiffer ride than without the TRD package.
