D100 pull my Duster?

U-haul is a very bad way to check what you can haul
“Very bad”?

So is asking a bunch of strangers on the internet, people with no “skin in the game” and little knowledge of the actual condition of the tow vehicle, for their opinions, any better?

While I didn’t call it out specifically (I guess I didn’t think it would be necessary), I only brought-up the Uhaul example to show there are options out there that don’t involve “doing the math”, as it were, and I seem to recall other car hauler rental companies offering the same service on their respective sites. Uhaul was just the first that popped into my head.
