I would definitely bounce this off CanAm. I would have a hard time not taking the towing guru's advice.

Regarding the ecoboost, I have major concerns regarding the long term reliability. Not only do you have another piece of expensive equipment in the mix, the turbocharger, but you are spreading the stresses of say 300,000 miles of driving and towing over only 2.3L of displacement versus the normal V8 displacement of 5.7L-6.2L. This may be why they don't offer it in the 3/4 ton trucks.

The usual limiting factor for a half ton truck is the payload. Assuming you have a weight distributing hitch, add together everything you put in the Tundra and 2/3 of the tongue weight to figure out what the payload is. Look in the Owner's Manual for the payload—it differs a lot for various Tundra models. Note that the tongue wt. for the Excella may be higher than claimed by Airstream because of the propane in the tanks, spare tire and whatever you have in the front of the trailer.

The 5.7 L. engine has a lot of power, and with ours I can tow an '08 25' Safari without any problems. I can tow over the high passes in Colorado without effort and very fast if I want to use enormous amounts of gas. We've towed our trailer without problems for around 45,000 miles except for having to replace the front rotors at about 70,000.

Tow ratings have dropped a bit with the new SAE ratings. Since the Tundra hasn't changed at all since '07, you might check those for the '13's. It is probably somewhere on the Toyota website.

Our experience is the Tundra is a well built truck, maybe even a 5/8 ton. But you have to research all the numbers. That means payload, what the tow capacity of the truck is and the weight the Tundra axles can carry. That takes some time and figuring out what things weigh.

I will have to agree that payload is the issue vs. towing capacity. These are two different things. With the TT/TV combination that you are proposing, you could easily end up well within the towing capacity while grossly over the trucks payload capacity.

For example, according to the Motor Trend website, the 2008 Tundra boasts a maximum 10,100# towing capacity. On the surface, this would put a 34' Airstream within specs. On the other hand, this truck's maximum payload capacity is published as 1,360#. A 34' Airstream is going to have a tongue weight of about 900#. This would indicate that if the truck had a full tank of gas and a 200# driver and nothing else, it would already be over the rated payload.

As far as a hitch system is concerned, I would take a serious look at either the Hensley Arrow or the ProPride. Granted these are expensive systems, but they work very well. With a marginal tow vehicle, a really good hitch system is important.

Just because one has towed an Airstream with a bicycle, doesn't mean you should!

I personally would look to a vehicle with a little more heft. There are times a 34 gets really heavy and can push you around.
I personally tow with a Ford Excursion, with Reese dual cam sway, V10, and the 4;30 rear end. It is a monster, and does not break a sweat!

The 34" is a monster, it is big to start with, has huge tanks, and will certainly get loaded up with stuff. I think you'll exceed your capabilities right out of the gate!

I recall only once wishing I had something a little longer, but for my needs, the engine, gearing, cargo space, and heft are all there.

I have towed all over, in all terrains. I love the Excursion, and wish they were still in production. I researched these for a long time and decided the engine would be the determining factor. The 6.0 was a definate out... the 7.3 is a GREAT engine, but at this point in time all the vehicles attached to that engine would be tattered and worn... the v10 has the same reliability, 15 mpg, and cheaper to fuel.
I like the vehicle you are wanting to haul with, but I think it's just a little under the task.

Good luck!

Depending on 4WD or not, the '07 Tundra Double Cab with 5.7 L. has a payload between 1,500 and 1,600 lbs. (I don't have the info in front of me). I believe the contents of the gas tank don't count against payload on Toyota trucks.

All good things to think about. I found that the payload is 1500lbs for this truck. We have 325 lbs of passengers and the Airstream PDF of weights states this has a younger weight of 800 lbs. if I do the math right we are at 1125 payload without any stuff, just people in the truck. That's 75% of the payload without stuff. Is that right?

Don't you hate the auto population of words. I misspell sometimes and it gets crazy. I meant the tongue weight not younger weight.

Sorry.

It's not going to roll over and die if you put 376 more pounds in the truck, but you will be living on the edge.

What does your WD hitch weigh, and did you calculate that in also?

The WD hitch distributes approximately 2/3 of the tongue wt. to the truck axles and 1/3 to the trailer axles. So, 533 lbs. against payload + 325 = 858 lbs. leaves 642 lbs for more cargo. But options may add weight to the truck—I estimated running boards and tonneau cover at 100 each. I guess different hitches weigh different amounts and I know the Equalizer is very heavy—more than 50 lbs., maybe much more.

Don't know the actual weight, but the ProPride shipping weight is 230 pounds. Hensley has to be close to the same.

Hi, the Ford Eco-boost is a 3.5 L V-6. [the Eco-boost in the F-150] But I think a larger version would be better for the 3/4 ton trucks. Maybe a direct injected, turbo charged 5.0 V-8 for the larger trucks?

Hi, although my Equal-i-zer brand hitch has worked great for my combination, I think the ProPride would be better for a 34'er.

These truck threads must be confusing to those who post a question. A couple of thoughts.

You are not "living at the edge" using the full payload capacity the truck is deemed fully capable of carrying.

The truck is designed to carry it's payload without the advantages of a weight distribution hitch.

The weight distribution hitch (in theory) distributes about 1/3 of the tongue weight as well as some of the weight of gear placed in the bed to the trailer axles. Every combination is different. The only way to know, if you must, is to load it and weigh each axle.

Of two trucks, both at full payload, one with weight distribution and one without, the one with a weight distribution hitch will be more stable and handle better because steering axle weight is returned, and the truck is balanced better.

There is never agreement on how much power is enough.

When the argument about truck size begins to neutralize, the big truck supporters will start to play the safety card, which is only validated by the quality of the driver.

The 2/3 and 1/3 estimations of transfer of weight by a WD hitch are just that. There are formulas to determine the numbers, but calculus is required to begin to understand them. So the estimations are used by those of us without engineering degrees.

The idea that truck capacities put out by the manufacturer are all lies to sell trucks may be somewhat true depending on the manufacturer. I have not heard of a flood of lawsuits over truck ratings so my belief is that there's not much evidence of lying. My experience with Toyotas is they are pretty accurate but that is my subjective analysis.
