I think there’s been a really important point that no one has mentioned yet, and that point being the weight of the tow vehicle versus the weight (mass) of what is being towed. What is the RATED tow capacity of this truck, as well as the GCVWR? Can the /6 pull it? Possibly. But are the brakes, frame, et al, up to the task?
As someone who has survived a “death wobble” twice in my life (once as a kid, the second time about 10 years ago), I can’t emphasize enough the importance of taking this into consideration.
To the OP: I agree wholeheartedly with
@fishmens67 here, and I no longer two anything “heavy” behind a light duty, 1/2 ton truck, “upgraded hitch” or no.
Edit add: There are formulas one can use to determine if a tow vehicle is capable of pulling a given load, but an easier thing to do would be to jump on Uhaul’s site and use their online towing combination tool. If the results come back negative, never assume you’re a REALLY good driver and/or are smarter than the Laws of Physics. Been there, done that…..don't ever want to do it again.
