I use the tow/haul mode whenever towing the Airstream. I believe that it is better for the transmission. I have done this with the Suburbans and their gasoline engines , and with the new Duramax. I realize that the fuel mileage may suffer slightly, but a few cents saved on gas is easily trumped by an $5,000 transmission repair.

Headed to the mountains Monday, so i'll be able to tell you a little more about The new truck and it's tow and hall in a few days. But with the 400HP diesel engine it is not going to be short on lugging power, especially when you consider the 800 lbs. ft. torque that this engine boasts. The 2006 F-250 with 6.0 diesel handled my 34 footer just fine in or out of tow and haul, but I usually ran in T&W for the trans. sake. The new 2011 truck has a oddity rear axle ratio, 331.1. I am interested to see how it reacts to towing.

Why settle for anything less?

IMHO, speaking as a 30 year transmission re-builder,
Most late model overdrive type automatic transmissions use clutches that are almost one half the size used for direct drive (3rd gear) for overdrive. Thus you are using half the total friction surface of direct drive that was only designed/intended to drive the weight of the TV along after it had reached highway speeds. This feature let the manufacturers reach increased mileage numbers, keeping the government and customer happy.
Adding an AS that weighs as much or more than the TV to this clutch pack (overdrive) puts a major strain on the clutches resulting in increased heat generated and if carried far enough clutch/transmission failure.
You might be able to get away with this practice (towing in OD mode) if your TV had plenty of power and you were in flat country, buy why risk it?
Transmissions are expensive to repair.
The reason you have tow/haul or od off as a selection is to prevent this problem. I would advise anyone towing/hauling anything of more than nominal weight to use these features to avoid future failures.

Always good to have the sage advice of experts helping me better understand the "why" of tow/haul. Thanks.
