Expectations for Towing with Toyota Highlander XLE AWD

Yeah, it will do fine with 3500 pounds.

Beware wind drag eats more power than trailer wight. And round trailers like the R-Pod aren't always better, because they increase the gap between the tow rig and trailer, which affects drag more than the shape of the trailer. Of course, total frontal area matters the most.

The reason the Highland isn't great for towing is because it makes its torque (and therefore HP) at a pretty high RPM. You won't be able to tow even a modest trailer in 8th or 7th. If you head into a strong winds, you might even be cruising in 4th or 5th. The motor is so smooth that alone probably won't be offensive, but it will be noticeable and it will cause it suck fuel. With with a 17-foot RPod, your fuel economy will only be the same as full size trucks puling much bigger trailers.

The issues isn't isolated to your Highlander. It affects all small-displacement non-turbo V6s. Even the 1/2-ton pickups. They make good power, just need to spin to make it. The 8-speed auto will ensure you'll always have enough HP, but it's history for towing is unknown so far.

Thanks for the replies.

Reviewing the specs for the 2018 xle awd, it has a heavy-duty radiator with engine oil cooler, 200-watt fan coupling, supplemental transmission oil cooler and 150-amp alternator (that's from https://www.toyota.com/highlander/features/mileage_estimates/6942/6950/6953).

I've been through the manual several times and it basically says stay within the weight ratings and be careful when towing. It recommends using a sway control device for trailers with a gross weight above 2000lbs.

According to the manual the v6 Highlanders meet the SAE J2807 standard for towing trailers up to 5000lbs. From what I've read the SAE J28807 tests assume a driver and passenger at 150lbs each along with 70lbs of hitch equipment.

Reading an article at Edmunds (https://www.edmunds.com/car-reviews/features/no-go-for-standardized-tow-ratings.html):
"Toyota was the first to begin certifying vehicles to the new standard beginning in the 2011 model year. It went all-in, too. Every model in the Toyota lineup has been rated according to J2807 since then."

I know the Highlander is designed primarily as a passenger vehicle and towing a 5000lb gvwr trailer seems unreasonable to me, but a 3500lb gvwr trailer seems doable as long as I watch tongue weight.

My 2008 Highlander (with factory tow prep package) towed trailers for 140,000 of the 185K miles I put on its odometer. Cargo trailers in the 6x12 size with weight up to 3500 lbs, a 17' Burro, and a 16' KZ E14RB. It did very well, the 3.5L had plenty of power.

You probably will not load that TT much more than 3600-3800 lbs if you're halfway careful about it. You will be traveling with a family, I assume, which is more weight in your HL than mine (I traveled alone). Even so, I would not hesitate to use the trailer you're looking at, except for one important thing: the hitch weight of 370 lbs. I'll bet that is dry, without the LP tanks or battery in place. Real world, you may have a difficult time keeping that hitch weight under 500 lbs once you load up. Not impossible to do, but you'd want to get a Sherline scale and check it before you left on any trip to make sure you're not overdoing it. And if you wanted to use a weight distributing hitch, well, they're another 70-95 lbs, so it'd be over for sure.

A friend had a 2014 Highlander and towed a Travelstar 19ck for years with it.

He towed from Ontario to Florida a couple of times and other southern destinations as well. He had no issues with it (family of 5).

The only draw back was the frequent gas stops...every 250km (150 miles).

I pulled my 3500 lb. TT with my 2011 highlander with tow package just fine.
you won't need a F550 like some may claim. and you are smart knowing you don't have to load it up to GVWR.

The Highlander is a CUV

First gen was based on the Camery

Second and later gen is based on the Sienna Mini Van

Just think of towing with a Camery if 1st Gen, and towing with a Sienna Mini Van if newer

Both monocoque/unibody, so WD Hitch system is normally no recommended (understand any OEM's 'recommendation' means no warranty if you do NOT follow their 'recommendation')


As Barney said, check your configuration and note that the MTWR is *NOT* an absolute. Meaning it depends on the configuration and loading of the TV. Again, check your glove box manual...as their should be an info page on towing listing the REDUCTION in MTWR with each passenger loaded into the TV

In my view, no matter what you get (other than a low profile basic pop up), you lack the motor to comfortably cruise except on flat terrain.

When it comes to towing, horsepower and displacement is still king.

No point in running 'the bags off' your Toyota. Get something sized for it. That way, you can take the stuff you want to along without fear of destroying your vehicle from overloading. Your excursions will be much more enjoyable.

Thanks. Sounds like I should stick to a maximum trailer GVWR of 3500lbs (for example, r-pod, winnie drop, camplite 11fk).

The closer you get to towing at or over your max weight, the more unpleasant your tow experience will be.

Couple things you need to look at:

1. Check the Highlander's owners manual. There are some SUV's that have a restriction on square inch or square feet of frontal area for high walled trailers, and some have restrictions on use of a weight distributing hitch.

2. Max tow weight is reduced by weight of any aftermarket accessories, passengers and cargo. If you need to use a weight distributing hitch, it will add 80 to 100 lbs of cargo weight and trailer tongue weight is also cargo weight.

3. Check the hitch receiver, it has it's own weight ratings, with and without weight distribution.

4. That trailer could have as much as 660 lbs tongue weight.

5. This statement is from the specs on that trailer "This weight reflects the rolling average unit weight for each model. Your trailer weight will vary according to optional equipment." The trailer could gain weight (maybe an air conditioner) at the factory, and it will gain weight (at least propane and battery) before it gets off the dealer lot. You should plan on that trailer being closer to it's GVWR.
