2007 Tundra vs F250 5.4

[Builder]

I don't buy gas engine trucks because they lack torque, they slow down significantly more than a diesel when towing, they get 20-25% lower gas mileage, even worse when towing, they don't last as long, they require tune-ups and most of all they bring far less resale value when you trade them in.

Ward's automotive did a study a few years back that determined diesel pickups bring in an average $5,000 more as a used vehicle than a gas counterpart.

So even though you'll pay $6,000-$7,000 more at purchase, you'll get on average $5,000 more at trade-in or resale.

So esentially it costs you ~$1,000-$2,000 more to own a diesel just based on purchase price minus trade-in.

Then factor all the savings on fuel, the reliability, longevity and superior performance in towing condidtions and the choice is obvious for someone who needs a HD tow vehicle.

My '07 360HP/ 650 ft lb DMAX & Allison transmission is the best motor/trans combo available in any pickup made today-Japanese, American, german, whatever.

If all you're doing is some light trailering, then get a gas truck and enjoy it.

Well I don't doubt that the Dmax and Allison are a good combo but they are nearing the end. GM will have to come out with something new soon or they will be left behind Ford and Dodge. The engine is nearing its limits and as we all know someone will have something bigger and better next week. I just wish GM and Dodge wrapped it with something better. I have always felt that the Dmax and Cummins fell short with the trucks they are in, not the engines. My Chevy and Dodge trucks feel apart way early. The Fords seem to take a beating and keep going and going. Of course we all think our trucks and equipment are the best. It is all in the eyes of the beholder. I like my women short with nice hips.

What indications do you have that the DMAX or Allison will be left behind by Ford or Dodge? If someone will have something bigger or better next week, then Ford & DC are in a worse position than GM. The last Ford diesel, the 6L, was an abject failure for ford. The 6.4L Ford diesel is brand new, yet unimpressive compared to the 7yr old DMAX design. You would think Ford would have designed it to crush the old DMAX, yet it has shown to be no better and makes no more power. It actually makes less power at lower RPM. Transmission? Allison compared to a Ford trans? GM has nothing to worry about.

In fact, the new 6.7L Cummins and the 6.4L Ford offer nothing better than the existing DMAX design. I think the DMAX has 400HP EASY left in it in a stock truck. I would bet bet it cranks out 400HP by 2010 model year. Heck, that's only 35-40 more HP than it is right now.

My GMC has met my expectations and I'm one picky guy.

+1, and I'm a happy Cummins ISB (2006, 5.9L, no EGR!!) owner.

The hp of the diesel pickups has reached a practical limit. A duramax GM pickup has hp comparable to many semis. No, I'm not claiming it will do the same work (it won't) but hp is not holding it back by any stretch. Many smaller road tractors make do with "only" 200-300hp and pull trailers of 20k or more. If you need more than 360hp for your task, you need a much bigger truck, or a better technique. The 3/4 ton and even 1-ton diesel pickups are already capable of pulling more than they can really stop or control - this is why Ford is now marketing the F450 to consumers. I think cost and fuel economy are the main items to improve, especially after the terrible 2007 emissions rules came into effect.

I like my Cummins too.

In the limited expierience I have, torque is king. Our first out Engine has the 8.9L Cummins. Only 350HP or so. The newest Cummins/Powerstrokes/Duramax beat that. But, they do not have the 1200+ft/lbs of torque.

While I'm sure a new Cummins 6.7 would power this Engine, it sure wouldn't pull it like the 8.9l, whether driving, or pumping.

Look at the body line of this toy with a trailer attached.

I am getting a 5th wheel hitch installed next week in my 07 Tundra. I will let everyone know how it pulls a 30 foot goose neck with a M Farmall loaded on it. That will be about 11,500 pounds, 1200 pounds over the rated pulling weight. It will be interesting to see what it will do.

Please let us know when you do this. I want to warn my wife to keep her and the kid off the roads that day. Sorry to be so frank, but you have absolutely no business doing this. My good friend has a towing and recovery business and hauls in wrecks like this everyday.

looks like that Toy has a week frame!

I'm always baffled when people assume more horsepower equals pulling power

torque moves things

hosepower is basically a measurement of the speed at which you make torque ie you can have an engine with 400hp and 400 lbs ft of torque and an engine with 400 hp and 800 lbs/ft of torque and the one thing you can be sure of is the one with twice the torque has twice the power at half the speed, while still having the same horsepower rating.


HP= (TORQUE X RPMS) / 5252

So true. I'd also like to add that it's just as important to check the amount of torque made at low RPM. If you look at some engines, they'll make more torque off idle, or "down low", than others. This gets the load moving from a dead stop better than an engine which develops torque at higher RPM.
