Tongue weight Estimate

My TV is a 2013 Tundra, 5.7L V8, towing package. GTWR is 10100 lbs.
I use a WDH rated at Max tongue weight of 1400 lbs and max gross trailer weight of 14000 lbs.

My trailer is a Springdale Summerland 2660RL.
Towable GVWR is 7645 lbs.
Hitch TWR 645 lbs

When the WDH is connected the axle weights are all below the max. The front of the truck goes from 36 1/2 in height w/o the WDH to 36 3/16 in w/ the WDH connected. That's a lowering of 5/16 in. The rear goes from 38 3/8 in to 36 in. So the truck is pretty level. The trailer is also level with the WDH connected.

That being said, can I assume that the tongue weight is within specs?

What are the specs on your Tundra's receiver hitch? (Not your WD Ball platform and weight bars, but the receiver on the truck.) Most of the Class IV's are rated 600# tongue/6,000# pull with WD.

You missed some of the most important info;
Truck gvw, gawr, gcwr and payload.

With a trailer gvw of 7645 anticipate a tongue weight of 915-1000lbs. Back to payload and receiver rating.....

Sounds like you have it dialed in fairly good. How does it tow?

That comment about Class IV hitch limits seemed a little off so I checked the info Reese has on their website:

Class IV hitches used for weight distributing are rated up to 14,000 lbs. gross trailer weight (GTW) with a 1400 lbs. maximum trailer tongue weight (TW).

Impossible to tell with Posted numbers. Take it to a scale and see what you have. That posted hitch wt. is without propane, battery, or any thing stored in the front compartment.

There's a significant difference in "dialed in" and "appropriately rated and dialed in".....

It "could be" (None of us can say with any certainty with the limited information available) that the hitch is adjusted appropriately, but the truck, trailer, receiver and/or hitch are not appropriately sized for the combination....

Sort of like saying I sighted in my rifle and I'm ready to go moose hunting.....

Without knowing if the "rifle" is a BB gun or a 30-06, it's impossible to say if the hunter has "properly sized equipment". Knowing that he can "hit the target" (dialed in) doesn't mean much if the equipment isn't up to the task at hand.....

That's true of some available aftermarket hitches, but the ones that come on most 1/2 ton pickups from the truck manufacturers are the lower end of Class IV.

I looked up a mid-range Class IV for the number I mentioned. There's valid info out there to support most any view point.

The OP needs to fill in the blank here by reading the sticker on his hitch. Other we're all just speculating and second-guessing each other.

I've ordered a Sherline LM-5000 - Trailer Tongue Weight Scale - 5000LB to get the actual tongue weight.

To answer another question on how it pulls. It seems rough to me. But, since this is my first trailer of this size I don't really know what to expect. Should it tow as smooth as the back bumper or will there be a little bump and kicking motion?

Please re-read my question. I asked for the specs on your receiver, not your WD hitch system.

I think all understand your hitch rating of 14k/1.4K. However, the receiver part of the hitch, the part on your truck, also has a max rating. This is not the same as the vehicle tow rating. There will be a max tow rating and a max tongue weight for the receiver part of the hitch. In most cases there will be two different numbers, one without WD and one when WD is used. These numbers will be on a tag on the receiver hitch itself and are very likely repeated in the owners manual. The entire system is only as strong as the lowest rated part and we haven't seen the ratings of all the parts.

There are no markings on the truck hitch. It is welded to the truck frame. The only thing I can find is in the owner's manual under TWR (Trailer Weight Rating) is 10100 Lbs. This with towing package.

The question at hand isn't which hitch you have. The 48069 is probably OK... The concern is that 2" square tube under your truck (the receiver) and what the decal on it says is the maximum tongue weight/trailer weight that it can carry.

ADDED: The fact that it's welded to the truck frame indicates that it's probably not OEM. That leads to questions about what else came with the truck from the factory (the rest of the trailer towing package). If you have the original window sticker or can get the information from Toyota with your VIN, then you'd know. My "distant guess" is that some previous owner added a aftermarket receiver of "unknown quality" to the frame. I'd be concerned with the other components in the towing package and if they are present, OEM and rated by Toyota for that 10,100 tow rating.

It should tell you in the owners manual what the hitch is rated for. Class 4 OEM hitch rating for a 2017 GMC / Chevy 1500 truck is 1250 lbs max on the hitch.

Edit : The payload for my truck however is 2080 lbs.

I talked to a Toyota dealership and the TV hitch is rated at 10100 Lbs. This is the Trailer Weight Rating (TWR) in the owners book.

To answer your question, No bumps and kicks while in motion should be felt. But, I am not really sure what's happening unless you explain it. When does it bump and kick? If your truck does that than the trailer I would say maybe it's the road surface.

Payload includes all the stuff in the truck box. You must have the Max Trailering package (NHT) to get that payload number (mine is 2,015)
