3.21 vs. 3.55

So I have been assured by members of this board that ecodiesel comes standard with 3.55 gears and 3.92 option. Looking at window sticker shows ecodiesel ,3.21 gears and nowhere else on window sticker does it show an upgrade to 3.55. Truck is a Big Horn and got me to wondering. If by some fluke the truck does indeed have 3.21 and ecodiesel how would the truck perform? My tow will be 11 foot tall travel trailer with 5000 lbs weight. What does the board think of 3.21 gears? I'm wondering worst case scenario. Thanks.

If you want more detailed information than what the windows sticker provides, you can ask the dealer for the build sheet. He will use the VIN number to look that up and it will show exactly all the features and options that were installed in that truck at build time.

I think the window sticker is more of a "comparison shopping" tool for consumers to use when walking around on the lot.

I'll let others answer the "towing with 3.21 gears" question.
