Lots of people do things I never would. 🙂 In my opinion, a better question is: based on my weights, what can I tow and stay within my ratings?
And that requires homework.
The tow rating is just one of a handful of ratings for the tow vehicle. Typically you’ll exceed the truck’s carrying capacity (called payload). This is the truck’s gross vehicle weight rating (GVWR) and the payload is the GVWR minus the truck’s loaded weight. The best way to find out how much your truck has is by taking it (loaded like you would for a camping trip- family, pets, crap in the truck bed, etc) to a truck stop and weighing it. Get the front and rear axle weights separately. What’s leftover is what you can carry for tongue weight.
After you check the GVWR, double check the rear gross axle weight rating (GAWR) and tire loading capacity against the scale numbers.
