Hope you all see what I did here.....

I believe the 25+MPG figure is Highway not combined. And that is what they are shooting for. also, It will surpass 8,500 pounds gross vehicle weight rating (GVWR), which renders it exempt from EPA fuel economy testing. Thus, no fuel economy numbers will ever show up on the window sticker

I believe you got the column headings backwards.

(That was my joke)

That comparison can look a little different too.

Actually I believe if you compare apples to apples, w/4.10 rear and extended cab, the 2500hd is 10,200 lbs max tow and 16,000lbs GCWR.

What I put in red was 4.10 gears and extended cab 2wd. The info I posted is for a 2015, not a 2014.

Ok, the 2015's are a little different with a 8 speed (I believe) and other changes that I don't know

Found the numbers for 2014 and they seem to be right in line with what the 15's are.

According to GM's website the 2015 2500 HD 6.0 gas v-8 is still using a 6 speed auto.

Anyway the op was about the new diesel not comparing a gas tundra to a gas chevy. If I was looking for a gas truck to pull the boat around or drive back and forth to work I would easily pick the tundra over the 2500 hd. If was going to hook a flatbed to it and drag around 6-10k lbs with frequency I would reverse that decision. The trucks are made for different purposes.

I stand corrected. I find it interesting that No matter what body configuration you select, the towing capacity stays the same... even when comparing a regular cab to an extended cab-long bed, where the weights are hundreds of pounds different, they have the same capacity. I don't think any other manufacturer does that. Just again proves that each manufacturer puts whatever capacity they want to try to win the arm wrestling match...
my point behind the post was to show that the tundra has more power, bigger brakes, more gearing, and is nearly identical in every other category than a modern 2500hd gmc and yet Noone considers it equivalent... Beggs the question. What actually makes a 1/2 ton different than a 3/4 ton? Because they put that sticker on them and charge more? Maybe a ecoboost f150 should be a 3/4 ton too?
Question: why does a truck that has less power,smaller brakes, less gearing have a higher towing capacity? And why does going from 3.73 rear to a 4.10 give you 4500lbs more without changing anything else?
Answer: because GM says it's so...they create the numbers...

And I am sorry for hyjacking the thread, it trended this way.

My 2000 3/4 came with E rated tires with a maximum of 80psi. Most if not all heavy duty trucks have heavy duty tires.

I'm not familiar with the Tundra but I think if nothing else it needs a different shoe.

I won't disagree with any of this. Much like the mpg figures, the tests used to be manufacturer-specific and are now standardized. They should do the same with towing specifications IMHO.

I thought they already did standardize the rating system last year or early this year didn't they?

If nothing else the tundra's max towing should be limited by its payload. Supposed to have 10-15% tongue weight. On a 13000 lb trailer that comes to 1300 lbs which is probably pretty close to max payload for some of the crew cab's. Don't forget you also have to include the driver anything else you have in or have added to the truck and if its a Gooseneck/5th wheel the weight of the hitch itself.
