Everything except the last 50 miles down to the coast is on I-5, with a 70 mph speed limit... So please get off your high horse, of course on 101 and the roads down to the coast we did not go that fast, and I got about 15 on that section.... (with in town driving, all loaded). So don't bring your kids into it, seriously.

Reread what I wrote, my toy hauler is a brick wall as I call it. Yes I totally get wind resistance, and that is why I get only 8 or 9 at 70 mph with the toy hauler, your v10 would be closer to 6.

I get 2 to 3 less mph at speed with that load than empty, so no it is not like towing unloaded. If you get within 3 mpg towing that load with your v10 I would be surprised.

I am not concerned with cost, my concern is going further between stops. Since I live in Spokane, and it sounds like you just came through here, you should get my point. If cost were my concern, I would have bought a 2002 7.3 or Duramax. Not a huge premium over the gas engine, and better mpgs. I frequently travel I-90 from here east through Montana to Billings, or to Butte and down I-15 into Idaho. There are very few gas stations on that route. My Chevy 6.0 gas engine would only get 140 miles per tank, I would imagine the v10 wouldn't be much more with my toy hauler loaded, especially in the wind you can get on that trip.

Yeah, that is an 08 GMC with the the Duramax. I get roughly the same mpg as my 6.0, a little less since it is bone stock. I got it because it was my time for a newer truck and the 6.4 Ford gets less mpg than the Duramax. Also, my wife drives my truck in the winter when I am gone a few times. She does not like how the Ford drives. Gotta keep the woman happy too.

Also, reread my comments. I have never said it is not capable, just not for me. I don't like revving to the moon and I don't like only going 180 miles on a tank of fuel. Yes I could spend 1,200 on a Titan tank, but that is not an upgrade I prefer to do.

Yes, techically it is the 6.2, but the principle of my comment doesn't change. The PSD is presented in dually and srw forms, and the dually is a little slower, even with higher gears. Doesn't matter what the gas engine is. Reread my comment... LOL

Man you guys are brutal today.

 

If you read the shootout from 2007...the Duracrap actually is a BETTER diesel motor than the 6.4L...what motor do you have in that girlie man bow-tie you are pulling that flat bed trailer with?

You can continue to bury your head in the sand...urr...hands...that is pretty obvious on how you roll.

Joe.



WOW A V10 vrs. PSD, Vrs. Duramax thread! Holy cow! Over a truck, really.....

 

Don't forget to factor in wind resistance... the rear wheels create a less aerodynamic wind profile, which also affects performance.

 

Hey Bare Bones, I hear you! 10,290 replies... That is crazy!

 

OK.....I was trying to friendly about it, you took an attitude.......Speed limit on I-5 in Oregon is 55mph for vehicles towing trailers, except 60 in a few select areas. I guess you are just another out of stater blasting through, dragging your noisy toys over to the dunes.......I am done with this and you.....Have fun.

 

This is the definition of a truck on Oregon:
"(A) A motor truck with a gross vehicle weight rating of more than 10,000 pounds or a truck tractor with a gross vehicle weight rating of more than 8,000 pounds."

My GVW is like 9,200 pounds, so I am not considered a "truck" in Oregon with that load. So yes, technically it is 65 for the speed limit, so we were doing 70 for that portion of the trip (and only 65 in Eugene and 55 or whatever in Portland).

I just don't like people on forums trying to make other people look like they are committing a crime or something or endangering their family, of which I did neither. And other than going 5 mph over, yes we obeyed all laws in Oregon, and you don't know me or what I contribute to the state of Oregon and the local communities I visit.

Go back to your bunker and reload, I am going back in a few months, you might need to shoot at me to save your family.

 

From your earlier comment:

Sounded to me like you were saying the V10 got beat by 5 seconds in the 2010 shootout.

 

Yeah, two separate thoughts, in the same paragraph. LOL I do that sometimes. The V10 got beat by 5 seconds on the 15% pull, in 700 feet in the 2007 shootout.

 

Definitely, and it would probably be very significant at higher speeds unloaded. But on a steep grade at or near GCWR, the majority of the load is due to the weight itself. Depending on the size and profile of the trailer, the DRW may not hurt that much. Without knowing the drag coefficient of both trucks (SRW and DRW) with trailer, it's impossible to say, but fully loaded on a 5-7% grade, I doubt that DRW would lower top speed more than a couple MPH--even less on steeper grades.

Here is my point, Look at the 7.2% grade, the dually with 3.73s was almost a full second slower than the srw with 3.55s and more than 3 mph slower. Put 3.73s on the srw and see what the difference is. And yes there is 2,000 pounds more on the dually.

So that example isn't the best, but look at this:
2010 HD Quarter-Mile Acceleration Test (Unloaded) - PickupTrucks.com Special Reports

Dually is about 2 mph slower on the 1/4 mile run, even with 3.73s vs. 3.55s on the srw.

so yes the weight and aerodynamics do mean something.

 

I track EVERY mile and gallon of fuel I drive/pump and hand calculate the mpg's.

My running AVERAGE for TOWING miles is right at 8mpg.

some tanks are less and some tanks are more but the AVERAGE for all those towing miles is right at 8mpg.

I drive between 62 and 65 on the interstate. My TT is a tall TT because of the slides so I fight wind constantly even on calm days.

I will drive 70mph when needed for SHORT DISTANCES. If you check the speed rating on your ST tires on your trailer you may be surprised what you find...


I drive an Excursion...the Ex has a 44 gallon fuel tank so I typically go 280 miles before stopping and I usually have 10 gallons left as a "cushion" in the tank. Plus I have 3 women in the truck and I can't hardly go more than 2 to 2.5 hours between "potty" stops...stopping at 280 or so miles on the odom means every other stop I stop for fuel and potty...of course there aren't many vehicles out there with a 44 gallon fuel tank...

Joe.

 

No, because I will still have stock nozzles on the injectors, so stock tune should be stock. But I do know that my truck right now with just a straight pipe and intake, will eat a stock 7.3L, especially low in the rpm band.


Oh, and last "hill" I pulled was 6% for 5 miles.....
Chances are I would be pulling a trailer, but don't know for sure.

 

Isn't the above statement a scientific contradiction???

If (x) motor has more HP AND more TQ it will outpull you period. Untill you throw gearing and tranny into the mix...... The only reason your V10 can hang with my 7.3 or 6.0 or 6.4 is because it can drop another gear or two, turn 50-85% more rpms, thus multiplying the torque created by the motor. It isn't the motor so much at that point, its the drivetrain helping you out.

A diesel will outpull any gasser in a 1 to 1 gear ratio every time.

My 7.3L just makes way more torque per RPM.

 

Jesus H toe tappin Christ. FINALLY, someone else realizes how stupid the whole V10 vs argument is. People in here pretend they're arguing motors when in reality they are arguing drive train PACKAGES. Completely different ball game.

 

When I haven't been at FTE for a while, I don't realize how much I miss it! This place is soooo entertaining!

Hey plgebbia, I used to have a really nice white '96 CC 7.3 truck like yours, except mine was a 4R100 truck. My little girl (she is a 12 year old gearhead!) still calls it 'The Early Superduty'. I would have kept that thing forever, but I got talked out of it by one of my friends. I still love those '92 and later trucks, and if I ever find another as clean as mine was I am going to buy it.
