Ahhhh. Opinions are like ass40les. Everyone has one. And some are one.
BTW, you might want to tell FCA they're wrong, or full of it, or whatever. I'm just going by what the VIN specs say, not the door sticker.
And like I said, it tows rock solid and level.
I fully understand why you think you can tow 11.5K pounds or whatever it says on the VIN. But the issue is that there are several ratings which limit you. There is the tow rating (which is 11.5K according to your vin). But there is also the very important payload rating which (for your truck) is < 1400 pounds (guessing, but you drive a limited and they are always low).
FCA doesn't say you can tow every trailer with 11.5 pounds. You can only tow 11.5K pounds, if the tongue weight of that trailer, plus driver/passengers/cargo is <= 1400 pounds.
So a boat that ways 10,000 pounds would do about 5% tongue weight, = 500 pounds. Theoretically you could tow a boat at 10,000 pounds.
A Travel Trailer that ways 10,000 pounds would do about 13% tongue weight, = 1300 pounds. That's a very close stretch and would already put you over payload, but hey, some might push it anyway
A 5w that ways 10,000 pounds would do about 22% tongue weight, = 2200 pounds. With your truck, thats almost 800 to 900 pounds over your payload.
So no, FCA isn't lying when it says you can pull 10,000 pounds. But it doesn't know what you're pulling. You can pull a boat at that weight, but not a 5w.
Different trailers have different weights on your truck, you need to make sure you don't exceed the second limit of your truck, payload. And you are most definitely over that by a large amount.
So please stop thinking everyone else here is the stupid one (me, FCA etc). Also please buy a bigger truck.
