You're towing a 3,000+ lb trailer with about 450 lbs of hitch weight. Do what you want, but you are advertising behaviors that are incredibly unsafe for you and your vehicle, not to mention the other people on the road with you.Towing my 18' Airstream at 70, I am only getting ~15 MPG, vs ~26 MPG normally. So far, we've made 3 trips of about 350 miles each, one way, so a total of about 1,000 miles. The vehicle tows just fine. No swaying or any hints that the trailer is too heavy. Still has plenty of power for passing. But it does use a lot more fuel.
Will vehicles just catastrophically collapse when you overload them? No. We tend to think in binary form. I put the trailer on the hitch and drove it down the road. It didn't explode into a fiery ball, so it must be OK.
Rather, go watch some videos of construction and power equipment failures on YouTube. This is a much better explanation of how overloaded equipment failures look: everything runs just fine ... right up until it doesn't. It's a slow, insidious process of failure where the metal, connectors, flex points, fulcrum points, and so on fatigue over time.
Not only do you not have the structural integrity (suspension, brakes) for such a heavy load, you're slowly damaging your BS as you drive down the road.
Again, do what you want. But this is way off the map for the BS' capability.
