This thread was about an efficiency comparison. Why all the belly achin' from so many of you that are obviously not interested? Move along.

Agreed. In my case I tow for a living in where towing economy directly affects my profit. Why others are afraid to let those that want to discuss fuel economy and towing economy makes no sense to me.

What I tow mostly is Airstreams & boats between 5 & 8k. A small diesel is perfect for this so I look forward to the Ecodiesel, F150, & GM small diesel comparison. If I did hot shot with a large GN with more 8 to 25k loads I would be looking at threads on longevity and towing economy for HDs.

Vern your in a different category from most here because you are towing for profit vs. plain old recreation. When there is a profit involved the entire perspective changes.
Most of us here just tow for fun. We fill the tank and head out for a relaxing adventure. MPG's simply aren't a priority in that scenario.
My goal is to have a safe relaxing trip. From the start RV'ing is not an economical activity. There are much cheaper ways to travel.
In the grand scheme of what I have spent before I leave the driveway, fuel cost are minor. If I save a few dollars in fuel will still only reflect a small % of my overall cost.
It gets even more jumbled when I try to compare my cost to others who: traveled a different route, in a different truck, towing a different trailer,at a different altitude,in a different climate, with a different payload,facing different winds, in different traffic conditions and at a different speed.
From all of this I'm supposed to make a meaningful conclusion concerning fuel efficiency.
Lastly throw in the lie o meters,and fudge factors and the efficiency analysis discussion maybe entertaining but it's not very accurate or beneficial.
