Not to mention autotrader.com. There's even one for sale in my neighborhood.

Oh OH Duh...don't know that I have ever seen one! Still loving the Excursion though.

I suspect that neither of you have driven one, so you don't realize just how good the 5.7L Tundra is. The big diesels are a lot better in terms of payload and towing grunt, but my Tundra tows my load just fine (I'll race you 0-60), rides much better empty and treats my Airstream better too.

Not sure why youd wanna race someone with an AS attached, but otherwise, my 460 big block tows my 31 footer just fine also. Funny thing is, our trucks make almost identical torque at the wheels lol. And I paid $20,000 less for mine. And mines American owned lol. Theres a few reasons Iv never drove one and dont care to

Is your Tundra stock? I've been kicking around the idea of adding a set of headers.

My Tundra is stock. I believe it has plenty of power and torque just the way it is. I suspect a set of headers may increase the performance some, but I am happy with the status quo. I worked on engine development as a student engineer while in college and saw first hand how the manufacturers try to get the best balance of torque and fuel economy.

I completely agree with you. We don't normally buy new vehicles, but when I found out that we could get an 08 Tundra 2wd for 25k (after a 5k rebate), it was a no brainer.

2001 F350
Regular maintenance, 225 grand miles 7.3, loud and proud. Will haul anything you put behind it, up or down. 19-2000 rpm best mileage ratio.

[ElCamino Man]

Hmm you must have a pretty good runnin 7.3. I know they can get 20+ unloaded (since pretty well no emissions) so 19 towing is excellent! Iv always wanted a 7.3 but chose the 460 due to price lol

On the mark!
We have gotten 14.5 mpg with our diesel ONLY when we tow (and the diesel planets / gods are all aligned) at 55 mph or under. As soon as we approach 60-65, the mpg drops to 12.5; what we do have is unlimited torque pulling the AS (or 28' dual axle sailboat/trailer) - the hills simply do not exist for the diesel Ram. The dealer told me again yesterday that at 10-15k miles we should expect better economy - seems like an excuse. When the warrany has expired, we will do the DPF delete and have spoken with others who experience a return to 18-20 mpg *even pulling weight* when they deleted the DPF on 2011 and 2012 models. Fortunately, we are not needing the DEF; so that problem will not need to be addressed with any mods.

We have an 08' 3500 with 58K on the clock, it did indeed pick up mileage, about 1 to 1.5 but not until around 25k miles. As in an earlier post, we get right at 11.2 pulling a bigger boxy toyhauler at 60 mph and hope for considerably better when pick we up our 25' AS next month.

[slowmover]

Even gasoline motors don't "break in" all the way until 30k miles. A Cummins will find best fuel mileage sometime after 100k given a fair amount of highway service (not all city miles). The curve drops off to incremental levels, but it is there.

[ElCamino Man]

15 mpg is definitly the norm for the 6.7s. Delete the smog bull and the skys the limit! Youll even see a very nice increase in power. Throw on a chip and set it to economy mode... I wouldnt doubt you can see 22 mpg unloaded

LOL, 30 years later I still have that drone in my ears from my 1969 427 Corvette. Custom side pipes with "no mufflers", and there was no towing involved, note 12MPG solo.

Times have changed. Now we drive/tow with a 6cyl midsized sedan that pretty much out performs the ol Vet any way you want to measure.

To the OP.... 13 to 14 MPG towing, 25+ solo with the 260HP V6 Infiniti.
