Not sure the 5.7 will last as long as the 4.7, but I'm sure it will last a long time.

4.7L was the largest Toyota truck engine before 2007. That year the 5.7 was introduced in the Tundra. In 2008 it was made available in the Sequoia, Land Cruiser, and Lexus LX.

Most of the Toyota trucks with the 4.7L or the newer 4.6L, like the Lexus GX, are rated to tow about 6500 lbs. Some of the 5.7L Toyotas tow 10,000 lbs.

I tow a 22 FB Sport with my 2003 4.7L two wheel drive Tundra. With the factory Toyota tow package it is rated for 8000 lbs towing. I have put a lot of miles towing over the years and I get ~ 16 mpg on the highway towing the AS. The 2 wd makes a difference. I live in the NE and use studded winter tires and have no problems getting around.

Great info in this thread... Wondering if anyone is towing with a later model 4.6L Tundra.

I'm planning to buy a 25FB this winter and I have a 2013 Tundra double cab 4x4 with the 4.6L engine and towing package. Rated to tow 6900 pounds. From what I'm reading here it sounds like even though I'll be at the very edge of the numbers, the truck won't have much trouble (especially if I add airbags or helper springs). I have four passengers, but wasn't planning to put anything particularly heavy in the bed -- maybe a kayak, a bike, and some camp furniture.

Still, would be nice to hear from someone who's towing the same unit with the same truck, just to put my paranoia at ease! I'm trying to dot every I before I plunk down the cash for the trailer.

A superficial Google search says 2013 4.6L Tundra has a tow capacity of 6,600 and a payload capacity of 1,550. And a 25FB has GVWR 7,300, dry weight of 5,500, and a hitch weight of 837.

Expect a loaded trailer to weigh 1000 lbs above its dry weight. So the 25FB will weigh 6500 which is only 100 lbs less than the truck’s ability. Subtracting the hitch weight from your payload capacity leaves 713 lbs for everything in your truck. If nobody weighs more than 175 lbs, you may be okay, but that leaves no room for a cooler with snacks, or lawn chairs in the back.

Meanwhile the 23FB has GVWR 6,000, dry weight 4800, and hitch weight 467. Now you’re towing a loaded weight of 5800, which is well within the truck’s ability, and you have 1083 lbs carrying capacity inside the truck for people and toys.

Or if you switched up to a 5.7L Tundra, the tow capacity is up to 10,400 lbs, which is well above anything Airstream makes. And a payload capacity of 2,090, which will carry the 837 lb. hitch plus 1253 lbs of people and toys.

I believe your Tundra will pull the 25FB, but it will always be at the edge of its ability and leave a zero margin of error. Get used to white knuckles.

Yeah, but to get that 2060 payload capacity with a 5.7 Tundra, one has to get a long bed, standard cab, 2WD model.....I bet very few people buy them other than contactors and other people wanting work trucks.

We pulled our 23FB with our 2004 Landcruiser. I am pretty sure that it has the 4.6 V8 in it. Power wise, and handling wise, it was no problem. As was mentioned the 23FB is a lot lighter than the 25FB.
The only real complaint I had when towing with the Landcruiser, was the small fuel tank and poor mpg. It seemed like I would start looking for gas about an hour after the last fill up.

Your 2004 Land Cruiser should have a 4.7 V8.
The 4.6 started in 2010.

I will be purchasing a 28ft airstream soon, along with a truck to pull this trailer.
I am the owner of many toyotas in my driving life, but am now looking at a Ford 150 or possibly Chevrolet 2500 for tow vehicles instead of the Tundra. I chose those 2 possible alternatives because of their payload capacity and their better than average reliability ratings in Consumer Reports. Has any of the Tundra owners, or prospective owners, felt like straying to a TV with the extra guts?

Nope.
Die hard Toyota fan here- would never consider anything else.
Please do some in-the-driver's-seat time in all of them.
Regardless of what it all looks like on paper, the Tundra 5.7 feels stronger than any of them as far as acceleration and power.
Maybe it's the 4:30 rear end gears and 6-speed?
It feels stronger than a Nissan Titan 5.6, a GM 6.2 with over 400 ft. lbs. of torque and over 400 horsepower on paper, or a Ford F150 EcoBoost. I have never driven a Ram or a new Ford with 5L or 6.2L or 6.4L.
I think after owning many Toyotas you could possibly be disappointed in anything that is not a Toyota.

Oh! now you've just gone too far..."feels" never works....but yes the rear axle ratio does matter, but what are the trans ratios?

Ford's 3.5L Ecoboost engine runs on 87 octane when not towing, but to get maximum torque for towing requires 91 octane.

Chevy does not have a gasoline engine more powerful than the Toyota 5.7L.

Simple examples: I've never had a Ford that didn't require annual service to keep the AC cold. I've never had a Toyota require AC service. Ford's multi-speed intermittent wiper control would be a joke if it weren't a continual thorn in the flesh. If Ford and Chevy's reliability are above average, then Toyota is nothing less than spectacular. It's the simple things that keep me coming back to Toyota.

Facts please: Is the 5.7 Toy over 420HP and 460 Torque?
Also check JD Powers dependability figures. Toy is very good, with some others just measuring tenths of a problem per 100 vehicles behind them. That is so close as to be imperceptible to the vast majority of owners.

However, old truths, become legends which persist...and the race goes on.

I was not aware that the 3.5L ecoboost has a recommendation of running Premium gas for severe duty/towing. I don't like that at all.$$$

A couple of years ago I went from a 2000 Tundra access cab 4WD/4.7 to a 2013 Tundra crew cab 4WD / 5.7. Mainly because my older son grew to 6'3" and he no longer fit in the back of the smaller cab... the extra power in the 5.7 is welcome but I lament the extra 1000 pounds of weight. As we restore our 25' Trade Wind, we'll keep an eye on the all-up weight so that we stay well within the max tongue weight limits, but I've accumulated about 12000 miles of towing both a SOB and flatdeck car hauler on the 2013 Tundra and there are no "extra guts" required, even on 7% grades. You can tell the trailer is back there but it's not like you're reduced to crawling up the hill at 40 MPH.

I can see where a person might want greater load capacity than what the current Tundra has available (especially if you're using the crewcab / 4WD variant like me) with the newer, heavier trailers; but if you can reasonably keep the tongue weight in the sub - 800 pound range (i.e. trailer weight < 6000 pounds) then the Tundra should be more than adequate and the straight-line performance is really only going to be a question of how much money you want to spend on gas.

My comment wasn't to "dis" your "feel" comment, but there is something needed to be brought up here about throttle feel. In the days of mechanical (cable most recently) throttle actuation, the response of the throttle body was linear, or in some cases, a smooth curve from closed throttle to WOT. With the advent of fly-by-wire, the opening of the throttle plate relative to foot pedal apply is a compound curve relationship....and is engineered for various end means manufacturer to manufacturer...and even between models within a manufacturer's stable. The curve can be manipulated to reduce the propensity for the consumer base to perform unneeded "jack rabbit" starts. This helps fuel economy. This is only one example of the type of programming done. There are many. They are computer controlled and differ in different gears, in TH mode, etc.

As a real world example. The 5.3 L seems to require a lot of throttle input to "get going", as perceived by the driver, but then...say after 1/4 pedal depression, it ramps up more aggressively. Some owners don't like that, but it really helps with city fuel economy.

Conversely, I wish my 6.2 L were a bit more like the 5.3 in throttle response. It ramps up more quickly off idle and, because it is so torquey, has a tendency to spin...particularly when wet. Even dry, it'll chirp when crossing the painted stop line or cross walks. Add a trailer, and a very light foot is required when pulling away.

I don't know if Tundra has gone to fly-by-wire yet, but every truck's "feel" is determined by the calibration engineer.

Not taking it as a dis-
Realizing throttle response could be as simple as the spring in the accelerator pedal-
I still love my truck and think is totally up to the task of hauling my Classic 30 around almost every weekend.
Whatever brand someone likes-
Whatever features convinced them one or the other was best for this reason or that-
Whatever you like will serve you well with good dependability, reliability, longevity-
The million mile Tundra has the now defunct 4.7.
I wonder if the 5.7 or 4.6 will ever have a million mile video on YouTube.
I honestly don't think the numbers are figured the same way from brand to brand- there is no standard unless all manufacturers have adopted J2807.
Otherwise it is impossible to compare apples to apples.
The Tundra only has 2 engine choices backed by one each transmission choice and one each rear end gears slightly different depending on 2-wheel drive or 4-wheel drive and tow package.
I opted for the bigger engine due to testosterone maybe, but it is a hoss.
Mine is a 2 wheel drive tow package truck.

Sorry, I was comparing only the two trucks he mentioned: Ford F150 and Chevy 2500. The 6.2L engine is not available on the 2500.

Just the facts: That model Ford requires high octane, and that model Chevy requires diesel to surpass Tundra's torque.
