Like the 4.10:1 gears, but Dodge needs to up the 5spd to 6spds like the others are doing.
Significantly smaller brakes provide better stopping distance than the Tundra.
Also the HEMI has quicker 0-60 times than the Tundra, even with a 5spd compared to the Tundras 6spd.
Depending on the overall quality, Dodge may just have provided a competitor to Ford/Chevy.

So can't say it's really a downside. Just normal anymore.

89 is a couple of cents more then 87, barely make a difference, but from what I understand, it will still run on 87 but with slightly reduce power. I guess that is a trade off of 10.5:1 compression

Running lower grade fuel isn't going to hurt the power in the 5.4l, which I do not beleave has enough compression to require a higher octane gas than 87. The only difference fuel makes on power is if you are running a normal motor with low compression and you get the bright idea hey lets run race gas (101 octane), which will actually hurt the power because the gas wont completely burn do to not enough heat thus not heating the air well enough. The only time you need a higher octane gas is when you are running a high compression motor. The reason you need a higher octane is so the fuel wont pre ignite from the heat during the compression stroke.

The 5.4ls run on a minimum of 87, unless Ford changed it for 09'. You should know, you have a 5.4l in your sig.

Unleaded Gasoline engines
Your vehicle is designed to use “Regular” unleaded gasoline with an
(R+M)/2 octane rating of 87. We do not recommend the use of gasolines
labeled as “Regular” that are sold with octane ratings of 86 or lower in
high altitude areas.

Here is the 1st release of the '09 F150 owners guide, which it also recommends 87 octane on page #373.

You think the 9.8:1 is high, just look at the 5.7L HEMI at 10.5:1 as lead head stated as does the article.

The CR on the 5.7l is way up there, no doubt helps performance out though. Should also lend itself to a healthy just in power with 93 octane and custom tuning. I just see many people may see that the Dodge needs 89 and shy away because they don't want to pay $.10 more per gallon for fuel, who knows. Ford has about reached the max CR with the 5.4l to run 87, at least with current EFI.

and as far as the new Dodge, I like it, I have a hard time parting with the cash that companies are asking for new cars though.

Don't know if it's due to the weight difference between the Ram/Tundra Or exactly what the case may be, but this is what the report stated, just going off what they said.

No you aren't missing anything. Usually bigger brakes provide better distance, but not in this case.

OK, I went back and read the report again, I missed a lot of pieces through out due to our puppy running around and harassing one of our cats.
it's definitely quite a truck and I would not mind having it in my driveway, if the price was right.

Vehicle weight plays a large role, as well.
