13' tundra 4.6L towing

My in-laws are selling a Toy Hauler and offered it to us at a insanely cheap price before they post it. It's a 20' NRG tandem axle with a GVWR Rating of 7900#, roughly 2400# lb max cargo weight, so I believe the trailer itself is around 5600-6000#.

I know my TWR is 8100# for my Tundra - 2013 4.6L 4x2 double cab with tow package - so it looks like I'm riding that line and understand a little more goes into it with it being a TT. Is this too much trailer or is this doable? From what I can find online my payload rating is 1450 lb for the bed. The trailer is equipped with a WDH

I'm not seeing a specific rating for tongue weight in the owner's manual, or on the trailer itself.

There'd be some camp gear, riding gear and 2x250lb dirt bikes and a 100 pw for equipment in the trailer. 500lb of family in the truck and probably a 80lb American bulldog if its not too hot.

Thanks for any insight,

Matt

 

That 4.6 liter is gonna be sweating hard..But it'll do it..

 

Trailer towing information starts on page 272 of the 2013 Tundra Owner Manual (see link below). A lot of good information there. Toyota recommends maximum tongue weight of 9-11% of TWR (page 282). A single axle trailer will likely be higher.

I looked up your TWR because it seemed high compared to my 2017's 6800 lbs. What I found was that your TWR should actually be 8200 pounds (page 278). Discovered the difference from my 2017 is the tow package, which increases the TWR by 1400 lbs.

Your payload claim of 1450 also seemed high for a DC. Be careful of online numbers for tow ratings. Check the tire placard on the driver side door jamb for payload and axle ratings (page 276). Subtract from the payload number any other weight additions from other mods you've made. Be advised that payload is not load allowed for the bed, that's the payload for the entire truck including passengers, luggage, cargo, and tongue weight.

Look up the manufacturers specified weight for the trailer. Add the weights of everything you want to put inside, and see how that compares to your TWR. Once you've loaded everything, probably a good idea to weigh the trailer to confirm actual trailer weight, and then verify tongue weight with a tongue scale. This will insure you are not over your TWR, and that tongue weight is still 9-11% of the loaded trailer weight as loaded.

 

Personally I would be ok doing this. As long as all your numbers are correct for trailer weight, tongue weight and all that and you are using a WDH and brake controller you will be fine. Even with that trailer fully loaded down you are within your tow limits with those given numbers.

 

Where are you towing it? Flatlands or mountains?

 

If he is towing in the mountains....it’ll Definetly sweat.

OP, before you really go for a long tow, inspect all of your cooling system...heat is the #1 killer when towing. The cooler the better, and the longer your engine/truck will last. By the way, congrats if/when you purchase the toy hauler! That is the best kind of travel trailer in my opinion.

 

It's still pretty fresh at 65k, so hopefully a little sweat is okay for now.

You're absolutely right. I was looking in my manual and it is 8200. I got the 1450 online but after checking my truck its 1335, - 6lb of upgrades... so I'm 1330lb. What can I say, she's pretty basic. Actually not even an SR5, I went to buy the work truck with the tow package and when I hoped in it had the sr5 interior but no badge.
For some reason that didn't click for me with when I was reading that section, thanks for the clarification on the % being applied towards the TWR, that makes sense now. That could be a factor if the load ends up being near the trailer's GVWR with the whole family loaded up. I need to make the drive out to Havasu and give it a test run, I'll try and find a scale out there and reference this to see if I'm good. Thanks for the input, very useful!

I'm located in Southern California near the coast so the majority will be near flat but just about everything fun is in the high desert past the grapevine or cajon pass. Both grades are about 6% at their steepest points for a few miles. I do love mountain camping/riding so might have to upgrade my wife's edge down the road if that's gonna tax my 4.6 too hard.

Will do! First trip will be a decent tow from Havasu, AZ back to socal but mostly downhills for the steep grades. I'll be going over the truck before hand. Thanks very happy to hear the truck should manage it if all lines up. I grew up riding dirt bikes and camping so I'm really looking forward to giving those same adventures/memories to my youngsters.


I really appreciate all the input, glad I found this resource. Thanks guys

 

Enjoy it man! You bought a solid truck, and it seems like you’re getting a solid trailer too! I do badly want to drive down to glamis/buttercup dunes. We love the Oregon dunes, but even those are about 8 hours away from us. SoCal is probably close to 17. And that’s with no stops. Someday I will make the pilgrimage down there!

 

Personally I think 4000rpm's is to high, but if it doesn't bother you, I say go for it...

I've done glamis a few times, it is a blast! We settled on Ocotillo Wells as a favorite when I was younger. That place is like disneyland for OHV toys. If you come down this way, dont miss out on that!

Yup, this is pretty much the exact set up and I swear that guys on the 40 coming back from AZ but could be wrong. The trailer is too good to pass up, I'm hoping my truck can handle it until we upgrade my wife's ford to something else. Not gonna put the fam in danger though, everything needs to check out and be within limits. I'm hoping to head out and give it a spin this weekend.

Thanks for the video, that's kinda what I expected being in the higher RPMS. He said thats a 4%, so I'd imagine the 6% of the cajon would be pushing real hard.
