Is My Terminology correct for my Tundra?

Please verify or correct my understanding of all these two numbers. I'm back to looking at a 23' CCD instead of the basecamp and want to make sure I understand everything correctly.

Tow Vehicle: '07 Tundra CrewMax 5.7L V8 4x4
Towing Capacity: 10,100 lbs
Maximum Payload: 1,515 lbs

'08 Airstream Intl CCD 23D
6000lb GVWR
Hitch Weight: 700 lbs
Net Carrying Capacity: 1,305 lbs

SO here's my questions:
1. The maximum payload on my truck is 1,515. so that's got to include people in the vehicle, as well as cargo in the bed. The Hitch Weight of the trailer counts against this as well, doesn't it???

2. the NCC is what includes all the water tanks and my cargo in there. Is there any concern with this once the trailer is parked and leveled and cargo being added in there and people in there? Or is that for trailering purposes only?

3. Also under the Specs on the Airstream site it says the GVWR is 6,000 lbs, but it also shows a GVWR of 6,300 but it says CSA, what does that mean? Is that an optional upgrade?

4. The towing capacity on my truck compensates for the trailer as well as any people and cargo in the vehicle, correct?

Thanks for the help,

Hi Ronnie.
Question 1: You've answered this question accurately. It gets tricky figuring what is the CrewMax's actual configuration. Payload figures only apply to the base model of a trim line; the manufacturer doesn't subtract optional items from the payload and you must do this yourself. You'd like to find if a 'tow package' is optional or standard. If the CrewMax only comes with a Class III/IV receiver AND the CrewMax has its own separate published specs, then you do have the full 1515# to play with. Probably add 150# to that hitch weight to account for up front weights of LP & weight distribution gear and the distributed weight of other personal loading inside the trailer. The manual will contain a diagram on how to actually weigh your hitch weight in the driveway (or see this).

Question 2: I'd say the NCC takes dynamic road forces into account and is for the purpose of travel. That NCC is quite generous and shows they matched the axles & trailer nicely -- not always the case on the smallest new Airstreams; eg, 16 footers. You'll be able to put personal/family gear & food in the trailer and still carry water for convenience and to keep the center of gravity low.

Question 3: CSA? Canadian specs possibly. Canada has different requirements. We'll see what other members say. You'll not exceed this # if you camp like an average person; ie, not dinging up the inside of your Airstream with firewood, dirt bikes and other heavy gear.

Question 4: Tow capacity and the TV's (tow vehicle) GCWR are somewhat intertwined. Tongue weight must be 11-13% of the entire trailer weight for a stable tow with U.S. trailers. To not do this would be unstable; eg, lighten the tongue too much and it's like throwing an arrow backwards -- a trailer tries to switch ends with potentially disastrous results. I find that payload will be the first limit stretched by too large a tow; ie, if aiming to stay within TV specs you will top out on the TV's payload usually before approaching tow capacity. Tow capacity seems set more by the advertising department anyway -- you can only tow that much if you burden the TV with a 90# thoroughbred jockey, a quart of gas and nothing more.

There are other online sources for tow information. Don't have those references right in front of me. Airstream has a good start at their FAQ page.

Thanks Bob. Toyota does specify the payload and towing for the specific truck configuration and my payload is lower than say the double cab.

I definitely see what you're saying about payload being the limit. I can definitely see that I would hit my payload limit long before my towing capacity. Especially considering that a lot of my trips will include possibly 4 people in the cab and 3 (50lb) dogs in the kennels in the bed. That's easily 700 - 800 pounds.

The 23 CCD seems to be a good little niche for me if i decide to go that route. Should be an easy tow with my TV, has a much higher NCC than the 19', with only a minor price increase.

hi rho

i agree the 23 (with 2 axles) can carry more and is a better living space.

yea csa is the 'canadian rating' usually the result of axle upgrades.

basically u r on the right track now...

the payload IS the limiting factor in your scheme with the tundra.

yes the tundra will pull a 23 just fine...

but 1500lbs is an issue as payload.

a/s tongue weight is only an estimate at 700lbs...

so with 800lbs IN the truck u are gonna be over 1500 lb for payload.

are u still planning to haul a 4 wheeler in the truck bed sometimes too?

so the gvwr on the tundra is ~7000 lbs with a curb weight of 5500+/-

that leave 1500 for payload.

but the gcwr is around 16,000 lbs meaning the total mass it can carry and tow all the stuff rolling.

it would seem IF you could increase the bed payload some that could help...

it would likely require a rear axle upgrade AND suspension upgrade to get more payload...

ah, camping...

so many toys and so little time!

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.

"so many toys and so little time"

Well said.

The 4-wheeler just won't be able to go if the trailer goes, have to go back to tent camping on those trips. Or invite someone else along for the trip and let them tow that trailer.
