The payload numbers in the manual don't account for any options that may have been added.

The door sticker accounts for any that were added at the factory and is more accurate.

Dealer or aftermarket options must be subtracted from the door sticker to get the most accurate payload.

I believe Toyota includes a full gas tank when they compute payload. That would be about 170 lbs. for a full tank (thus, you can add most of that to payload by running on fumes all the time; as practical as only driving downhill).

TouringDan, that was impressive! In a few weeks my wife and I will take our first trip pulling our 1973 27' with a new to us 2012 5.7 Sequoia 4x4...I have been stuck and the 4wd gives us peace-of-mind. For the last few years we have towed it with a 2003 Tahoe 5.3 with mpg ranging from 9 to 12 depending on speed. Before retiring part of my job was leading summer backpacking trips through the mountains and I learned to limit what I thought I couldn't live without so I could include extra food for kids who ate everything the first night. I was amazed that my pack weight went from 55 lb to 26 lbs. My wife and I have tried to apply this travel light mentality to our RVing and are still adding and subtracting items. I have slowed our speed to around 60 mph and my question is what is the approximate difference in mpg for 55 and 65 mph. The frontal area of a Sequoia and Tundra are about the same although I realize other factors are in play as well.

Well, I guess that rules out that truck for me. I need my stuff on those long trips. Guess I'll keep feeding fuel to the beast!

I can get by with a 1/2 ton truck if I get the max towing package, but it is right at the limits of my payload needs (1,900+/- lb). I am thinking about going back to the 1/2 ton when the 8 speed transmissions become more available.

Alan, different models have different payloads—with 2wd, fewer options, smaller cab, for ex., you can gain quite a bit. Some models were over 2,000 lbs. Best to check Toyota's website to get all the possibilities. In a few months or less we'll know what the redesigned '14's are like.

I would estimate that the fuel economy change in going from 55 to 65 mph would drop by about 20%. The best way to determine the change is by a test. Reset the fuel economy meter and drive 25 miles with the cruise control set on 55 mph. Then reset the fuel economy meter again, increase your speed to 65 mph using cruise control, drive 25 miles and compare the results.

The 1,680 figure should include all factory options as it was specified for the SR5 package and the 5.7L motor (which included the tow package). The only other option I installed was the bed cap (about 200 lbs).

Of course the best way to determine your real payload is to weigh the truck with you in it and a full tank of fuel and subtract this number from the GVWR of 6,900 lbs (for my truck).

I would not expect any change in the payload numbers for the 2014 Tundra since all they changed is the cosmetics, but we can always hope for an increase in the payload. I don't think that Toyota is particularly concerned about payload since most consumers only care about how much they can tow. They don't realize that they will be exceeding the GVWR and the RAWR long before they exceed the max trailer tow rating.

I don't trust the computer readout on my 2010 Tundra SR5. Its not all that accurate. Calculating the mileage is more accurate if you take the odometer reading and divide it by gallons pumped the next time you fill up. I just use it as a trend gauge, if it goes up I'm getting better mileage than before.

Thanks, I will do both. I have never had or used a fuel conservation meter before but am looking forward to using it and hope it will improve our mpg.

Tundra towing FCloud 30'

You will be very happy with the Tundra. Our 2008 IForce V8 tows our new 2014 FC 31' like a dream. I will never own anything else for towing. Good luck.

The payload of the Tundra is in addition to the weight of the driver and a full tank of fuel. Don't know what they figure for the average weight of the driver. But I am sure that I am north of it. If you know what I mean.
The Tundra is one fine TV.

I just finished towing my Tradewind about 200 miles to DC to see my daughter and camp 3 days at Greenbelt Park, about about 12 miles from DC. I normally get about 13.5 mpg, but on this trip I took some back roads with very little traffic, hence no stop and go to affect fuel economy. I got 16.1 mpg on the trip to DC and 14.5 mpg on the trip home for an average of 15.3 mpg. I drove gently with speeds between 50 and 60 mph. Now what surprised me was that for the 125 miles of solo driving with some stop and go and some heavy traffic I only got 11.9 mpg, less than my towing mileage. It is no wonder that I think my Tundra is a great TV! Just so you know- 2008 5.7L, SR-5, double cab, Leer cap, 6 speed, 2wd.

If you are relying on the computer for mileage figures. It can be off by quite a bit. Especially when in traffic.
The acceleration from each stop costs you mileage.
My '08 Tundra 5.7 Double Cab gets exceptional mileage. IMHO.
I have noticed as the fuel gage drops the MPG seems to go down slightly. Not sure how the fuel consumption is calculated. Does the computer use the fuel level gage as an input? Does it use the throttle positioning sensor to determine the amount of fuel at a moment in time? Does it know when the truck is in gear? Thus only do the calculation when moving? Obviously the odometer is in play. So as tires wear they get somewhat smaller.
The condition of the air filter can also affect MPG.
So many factors in play.

Note: Toyotas count fuel injector pulses to estimate the amount of fuel used; and this derived amount is used with the odometer reading to calculate the mpg displayed on the dash. Variations in injector volume between vehicles result in slight differences in fuel economy displayed, versus actual mileage.

Payload

The below photos show my GVWR and load labels from my 2010 2wd Double Cab Tundra with 6 1/2' bed.

I notice the GAWR for the front is 3900lbs with the front tires at 30psi and 4100 for the rear with the tires at 33psi. My tires, Michelin 255/70x18 can be inflated to 44psi with max load of something like 2164lbs per tire. If you add the front GAWR of the rear and front then it equals to 8000lbs. My question is if your tires can handle the weight then as long as you don't exceed the GAWR for each axle is it possible with a WDH to keep the GAWRs with parameters yet still get more payload than the yellow sticker. I haven't weighed my Tundra yet so I'm assuming the unladened weight of my truck must be within 500 to 800lbs of each axle. My labeled payload is 1465 and my GVWR is 6900 so that must mean my truck weighs 5435lbs.

When looking at the definitions of the HD Payload package of Ford F150s it seems the only thing that is changed is the shock absorbers and tires to 245/75x17 LT tires. They don't mention changes to springs or axles parts to support the increased weight.

I've got my heavy 2008 Classic on a Equalizer WDH and with 5 washers I have 37" from ground to fender over each tire.

Can anyone post their load labels from a 4x4 Double Cab 5.7L Tundra or post the GAWR and payload numbers.

I have an '08 Tundra, same model as yours. The truck with a full fuel tank weighs 5,460 pounds.
I don't think you can use a WD hitch to increase the load carrying in capacity of your truck.
