Newbie: Towing TT w/ 2008 Toyota Sequoia

The camping bug bit my wife over the summer so we decided to attend the RV Expo in Boston over the past weekend. She fell in love with the 2018 Rockwood 2706WS and after two days of looking at smaller options, we decided the Rockwood fits our family best as the 3 kids are growing fast. I remember looking in my Sequoia's owners manual before the show for the towing capacity and all I remembered was 9000 lbs. Although seeing the GVWR of 8800 lbs for the TT scared me, I convinced myself the Sequoia can handle it as I wouldn't tow with potable water. I obviously should have done more due diligence... So after spending the morning researching towing with the Sequoia, and how to calculate the weights using the TV & TT ratings, the main takeaway from the research is that Toyota has downgraded the max towing capacity of this TV to ~7600lbs applying a new standard (J2807). This has been well documented in other posts. So I've come up with the following calculations for my set-up:



So, sanity check time:

1.) I made an assumption on my hitch weight based on Rockwood's publicized 804 lbs assuming they got that number using the TT's GVWR. Is that reasonable or should I have just used the 804# number?
2.) I did purchase a WD hitch but I don't know the specifics (yet). Do these really weight a few hundred lbs? If so, I definitely need to include that in the calcs.
3.) For the experienced towers/campers that actually weigh their rigs, is 950 lbs. of dry cargo even a reasonable number for a TT this big? I would assume we have to pack incredibly light... and that may be a challenge knowing my wife.
4.) What other thoughts do you have besides the obvious I need to upgrade my tow vehicle? Will do so in time.

According to the Trailer Life 2008 Towing Guide, a 4WD Sequoia has a trailer rating of 6200 lbs.

I think that puts an end to any further discussion of this TV/trailer combo.

BTW, my 2500 Burb is maxed out with a trailer weighing 8600 lbs.


Trailer life is wrong. Toyota’s specification chart for that year show a range of weights depending on engine and trim level. The lowest rating is 7500lbs for the 4.7l 4x4 SR5. Max is 10k for the same in 4x2 with the 5.7l. Lower ratings didn’t happen until the 2011 model year when Toyota adopted the new SAE2807 standards. GCWR are from 16,960 to 17,280lbs. Odd that it doesn’t list GCWR for the upper trim levels though.


Ok, let's take a closer look at the sales brochure:



Can someone PLEASE explain to me how you're going to tow a 9100-lb trailer, when the best possible payload rating of any configuration is only 1380 lbs? Last time I checked, I'd expect a 9100-lb trailer to have about 1180 lbs of tongue weight. I hope the driver and passengers are really small people.

Trailer towing rating is useless with most SUVs - the limiting factors are most often rear axle weight rating or payload. At least my Suburban has a payload rating of 2088 lbs and a RAWR of 5500 (though AA rates it to 10k in other applications).

No that's not the ONLY thing you can do....get it home, pack it up, and then run it up to the closest scale. Look for a CAT Scale, or a local moving company or recycler. Heck, our town dump has 2 scales, they weight you on the way in, weigh you on the way out, and charge you by the ton....

Take 3 weights as I mentioned (still weight the Sequoia by itself so you can calculate tongue weight).

Scale weights get you out of spreadsheet land where assumptions are required and into the real world. As I said, it's not just what you bring, but where you put it in the trailer, that will affect tongue weight.

Weight added behind the TT axles lightens the tongue...you are looking at worst case by all the weight added by batteries, hitch, and propane...also consider what may be lightening the hitch. the situation may not be as bad as it seems...or it could be worse...

See where the fresh water tank is...if the tank is behind the TT axles, you will actually lighten the tongue by adding water, even though the trailer will weigh more. As I said, don't make assumptions, get the trailer and weigh it.

Once you have good numbers, then you can shop in the know for a new truck. WORST thing you can do at this point is buy a new truck before you weigh the trailer, and then wind up buying a new truck that's STILL under-rated because your assumptions were wrong.

IMHO, best to use the OEM’s info...instead of a non-OEM source...which has a copy/data-entry mistake potential. I’ve found too many issues from 2nd/3rd party sources

Toyota 2008 Sequia brochure

Only missing info seems to be GAWR’s

As most have advised...load up ready to go RV’ing and weigh it axle by axle

Then do the simple math....generic formula to figure : GCWR >= TV + Trailer+ stuff (actual weights)

RGAWR is needed to check if enough “R” vs what it will be asked to handle

Most half ton’s RGAWR are in the +4K range. Higher class TV’s are in the +6K range. Most weight goes on the rear axle...just take a side view most TV’’’s.....mid point between front axles is at the read edge of the drivers door

Decide if you, the OP, believes in the ratings system or not

If yes, gather the specifications and follow them

If not, then academic this thread...

If just looking for the “sure you can”....then you the OP have it, but know only one person is responsible for the setup and that is the driver....none of us advisers have any skin in your game

The payload ratings on diesel 3/4 ton trucks mean literally nothing. They're heavy but class restricted to a max 10k lb GVWR. That's why most "5th wheel guys" use axle and tire ratings to determine carrying capacity for that type of truck.

Interesting find. My 2010 hard copy owners manual does not match all those capacities shown on that old brochure. Nothing over 9100lbs.

You could not be more wrong. My set up doesn't get any more solid until it becomes a real 5th wheel.

I know this is very hard to believe for most people, but I am not exaggerating. 70 mph was my cruise speed, I had no sway or wiggle at any time and mountains were not a struggle at all. I counted 3 times I dropped to 3rd gear and held 55mph thru some of the most mountainous interstates the US has to offer.

BTW, nearly everyone is wrong about the Sequoia's tow ratings.

The Sequoia's top end tow capacity is 9100lbs prior to 2012...when it dropped to 7300lbs via SAE performance test.

GCWR was 16,500lbs and is now 13,600lbs

That’s a heavy tt for its size. Mine is bigger, with 2 slides and weighs 250lbs less delivered, including options, propane and battery. You may be able to find the same or similar floor plan in a lighter trailer from a different brand. There are a lot of trailers made by the same manufacturer but branded under a different name. Layouts are the same but components can be different and weights vary. Some say lighter equals cheaper but not always. A friend has the exact tt as mine but under a different brand. His dry weight is 1k heavier than mine! Not sure where all the extra weight is but we agree that mine is of better build quality and has had less issues.

Hopefully you and that brother in law are friendly and he lets you borrow his F250 frequently so you can enjoy that trailer

Hey...you & brother in law can do a couple of camping trips together
Is it time for your medication or mine?

10-ply rated tires at 80 psi, 35 mph max, WDH with good sway control, 4 MPG, Aggressive electronic brake controller (Prodigy), super wide tow mirror extensions...

Go easy and you'll get it home. But remember, the tail end is WAAAAY back there 😉

If you like SUVs and don't want to spend a fortune, consider the Ford Excursion. Out of production, but a huge market for used- especially 7.3L diesels.

Also have 6.0L diesels but have to know what you're doing because of the 6.0L diesel problems- or someone who does to check it for you.

Then there are v10 gassers

Ford Excursion was the world's largest production SUV. It still holds that title.

But it doesn't have all the updated electronic spaceship style interior of the modern trucks.

Glad you asked the questions before being worried and disappointed in the towing performance of your current combination.

Good luck!

Paper calculations kill most large trailer for the Tundra and Sequoia and most 1/2 ton EVERYTHING.

Only 1/2 tons (like the F-150) with MAX PAYLOAD (not to be confused with max tow) will get you clear of most payload issues when traveling with a family and large TT.

You'd be surprised how many 3/4 ton trucks are hitting near the same limits and many of those diesel engines rob enough payload to drop it into the 1/2 ton range of 1800lbs. FAR too many 5th wheel guys dont care about this and tow with pin weight that exceed payload and thus puts them way over GVWR.

When you're on edge and so close to max on paper with a TT (close or not dramatically over), you really don't know exactly where you are until you hit the scale WITH THE WDH FULLY SET UP FOR YOUR LOADED TRAILER.

Below are my actual loaded scale weights, complete with exactly how much weight is transferred. It clearly shows that with the WDH NOT HOOKED UP, I am over spec. With the WDH connected, I within all specs.



Here's the Tundra and Sequoia specs line by line. While the Tundra gets beat up for low payload, in reality its the practically same as most all 1/2 tons (and even more than some). Again the clear exception is those with the max payload option.




SO. If you really do NEED a bigger truck...go big or go home.

OR. Shop for a smaller/lighter trailer.

Finally....do more research on the Hensley and Propride. Big money. Both have their quirks. I love and hate them at the same time. But they are worth every penny for absolute stable towing (even with a short wheel base SUV and LONG trailer!!!) and in the long run saves me thousands.

I would not have traveled across the country with my family if I didn't feel 100% safe doing so and had weight slips to prove I'm "legal" should anything happen.

That said, my setup is not for rookies. Nor is a 32ft TT in my opinion.

Trying to the find ways to lower the trailer's gross tongue weight just to better accommodate your Sequoia's limited towing capability is exactly what you don't want to do - too low and you could easily be all over the road, particularly with such a long trailer and such a short wheelbase vehicle. :E Rather, you should be aiming for 13% - 14% of the trailer's average gross weight, loaded & ready to camp, and if it's too much for your Sequoia, then it's too much. 😉 Bottom line - doesn't matter what you do to try to rationalize it this trailer you want to tow is 3/4 ton truck territory - anything less just won't cut it.

OP, this trailer is starting out with a very heavy hitch weight for our Sequoia.


I'm definitely starting to see the problem. Assuming a max cargo (hitch) weight of 970# taking just me as a driver into account, I'd have to keep the hitch/axle dist ratio between 11.4 and 12.4 according to a quick spreadsheet (which also jives with online calculator). Given that the TT starts out at 12.1% dry, and that doesn't take into account the WD hitch, propane, battery, oh and I don't know, the massive pass-through storage this unit has right behind the hitch, I'm unlikely to improve upon this distribution ratio. It's very likely to get much worse. Never mind the fact that even if I could magically keep it between 11.4 and 12.4, all those scenarios exceed my goal of keeping trailer weight 7600# or less. It ranges from 7800-8500. The only thing I think I can do with the Sequoia at this point is tow it home dry/empty.

Thanks for everyone's help.
