Towing 7000 LB trailer?

[ADA6969]

Hello,

Anyone towing a 7000LB+ trailer with a 42"+ extension With out weight disruption. How does it handle? My 28" worked great. Just wondering if 14" makes a big difference. Keep it clean people.

Thanks, Andy

I’ll check back later with popcorn.
Should be a really good conversation by then!

FALSE!
Tongue weight will increase drive axle weight by TW plus the weight transferred off steering by leverage.
To know the TW you need to subtract GW of the truck from GW of the combination to get weight of trailer. Then subtract the trailer axle weight from the calculated weight of trailer to get TW.

Unless it is a very specialized trailer it's going to be tough to get the tongue weight down to 400-500lbs and have a stable tow.

We still don't know the trailer model.
When boat trailers track with 5% load on tongue just fine, typical cargo trailer will be prone to fishtailing with this weight distribution.
How sensitive the subject can be, on the mentioned cargo trailer I was carrying small bulldozers.
When I load it with plow forward - the trailer drove rock solid.
When I loaded it with plow to the rear - it become wind and road crown sensitive.
I observe to have load COG at right place all the time, so the difference was in air drag.

With the truck weight at 12300 28" ext. I would only run about 400 lbs. on the hitch. New camper truck will be over 13,500. I would think I can run 400-500 lbs. on the hitch w/o WD Even though trailer weights 7500LBS ??????????

Your truck weighs 12,300 lbs???? Thats a big heavy truck.
at any rate, with a 7,500lb trailer. your tongues weight should be well over 800lbs. I don't know how you are going to unload the tongue to 400lb.

You can be scared, but the videos have nothing to do with your questions though. Just like masks ...

Just watched the video. I have been towing my current over 40k miles with no problems 75 mph winds etc. Just great After watching I am scared now. Mite need safer hobby

I have 2 types of tongue scales one built into hitch very cool

I can watch THOSE VIDEOSendlessly.
They would not be so funny if I would not see similar in real life.
Notice that almost none of the drivers applied brakes in the situation.
I bet they don't wear masks in pandemic neither.

Per my experience the poor towing is mostly due to trailer configuration, not the hitch.
I did tow my patio boat with 48" stinger just fine, even we had strong winds coming back. But my boat was about 3000 lb and boats are good for towing without WD.
Than in the past I had 18,000 lb equipment hauler trailer who never needed WD.
I thing it was tracking without fishtailing mostly due 3 axles, but there is more to it.

Super truss at 42" without a WD hitch can only handle 600 pounds of tongue weight and 6000 pounds of pull. with a WD hitch it can handle 1200 TW and 12000 pull

I pull a 7000 pound horse trailer with a 48" extension and a WD hitch all over the country with no complaints. In the last 12 months I did round trips from San Francisco to Lexington Ky and From SF to Chicago round trip in rain wind snow and heat. (KY in Nov, Chicago in July).
