Calculating fuel cpm is the point. The overall cpm is much higher, thus not shown.

Sorry RED, I missed your point. Agree that fuel cpm is fine for estimating that aspect of your trip cost, (like food cost per day). It is not meaningful for the vehicle efficiency comparisons in this thread.

The bottom line of fuel efficiency is out-of-pocket cost to get the job done, or it is meaningless. Why spend $50,000 to get a few more miles per gallon, when you can get a less fuel efficient but capable tow vehicle for $25,000?

This is the question is asked myself when I compared a VW Touareg TDI with a Dodge Ram Express 5.7 gas, and bought the Dodge.

There are many similar examples. Fuel efficiency can be very expensive.

03 F350 CCSB SRW, 7.3L psd bone stock 4x2. I tow a 1990 29' Excella. I dont have an exact figure, but its in the 13 to 14 mpg range on long trips. I rarely see much better thank that.

I usually budget my trips using a 12 mpg figure, to error on the side of caution. That way I usually end up with more fuel than I planned for.

I didn't buy for fuel efficiency, just diesel power (and hopefully a more reliable diesel from Ford). The somewhat unexpected amount of fuel efficiency from this vehicle is an added benefit I thought I would share for others in the market for a TV. (btw my 250 is a supercab short bed; 142" wheelbase)

Ha ha...I've got the lightweight vintage AS and the twin to the Touareg--a Porsche Cayenne Turbo. It's far from a diesel though and at $4/gal for Super I don't even want to know the "cpm" calculation. ;-) I must say though that `10-11 mpg at a consistent 70mph from Colorado to Arizona was a pleasant surprise considering the 16-17mpg I usually get unloaded at much faster speeds.

Oh, and the P-truck is 6 years old and cost much less than ANY newer TV. Factoring in the (lack of) depreciation and cheaper insurance for a 6 year old vehicle, I'd guess I am probably running the equivalent of somewhere around 20cpm. Not as good as many here, but I am having just as much (or more?) fun!

Doug,
You compared an apple with an orange - those two vehicles couldn't be more different. Selecting a vehicle, particularly if towing is not your sole or even primary usage, involves many more factors than mpg. Enjoy your Dodge - I really enjoy my Jeep CRD. Different tastes.

For the purpose of tow vehicle and easy daily driver at destination, the Dodge Ram and VW Touareg TDI are quite similar, at least for us. Both have adequate power and rated towing capability, both are relatively short wheelbase for getting around town, both drive and ride comfortably.

The difference and deciding factor is in fuel use/cost which is not huge, and initial price, tax, license, insurance and maintenance costs, as well as money either tied up or paying interest. It's a guess what the difference will be over the long run, but we found the Dodge Ram Express fully equipped for towing and nicely outfitted a great bargain.

We keep a VW Jetta TDI at home for use without the trailer. The Touareg TDI can't come close to that in fuel use or cost of ownership either. The Dodge and the Jetta together cost less than the Touareg, all bought new.

So whether apple or orange, they are both good, but one costs much, much more to do the same job.

I just completed a 5,000 mile trip to Yellowstone and back. Even with the kayak on the roof I averaged 17.2 mpg towing (calculated). I kept my speed at 66 mph. My previous F-150 couldn't even get that EMPTY.

The highest I've seen with a tailwind was 19.1 mpg and the lowest going into a strong headwind was 14.2 mpg. I've towed about 12,000 miles this year and couldn't be more pleased with the Touareg TDI.

Yes Steve, small diesel is probably the future of towing. I wish VW or others would produce a lower priced utility version instead the fancy models for us that just want a tow truck.

Who is going to pony up for the 2013 Porsche Cayenne DIESEL! 7500+ tow rating!... ok very similar to the Toureg, but still.

... Once you tow with a diesel it is hard to go back to gas.

Great looking setup TinLoaf!

Ahh, you raise another factor. In retirement, with relatively high vehicle taxes in CO (not to mention insurance and maintenance - part of the all-in CPM), we've decided to be rather practical and own only one vehicle. Even that one sits idle for five months while we are sailing. Our 08 Grand Cherokee MB Diesel (yes, the $$ fully loaded model) does it all for us. 23.5 mpg avg. 15-17 mpg towing, goes anywhere in comfort. 80,000 miles so far, 26,000 towing. We're waiting for the upcoming 2014 Jeep GC Diesel. So, it depends upon how you define 'the job' in your terms. The real bottom line, IMHO, is personal satisfaction.

Ahh, you still have two vehicles, a Jeep and a boat, one of which sits idle for half the year.

dk,
True, and I'll never tow the Airstream with the sailboat. The mpg would be exceptional if I could, however

Good point. We decided as retirees, as well, that we could get by with one vehicle; in our case, a crew cab Toyota Tacoma. It works for most things we could want.

Question

11.2 to 12.5....why?

I used to obsess...but I grew out of it.
