Typically 70. It's stable faster than that, and I can stop about as fast as I can with my trailer with brakes.
But I'm in a Cummins Ram 4 way disks with ABS. It's a heavy, solid truck and there is no way the pinz is going to push it around.
What people don't understand about flat towing is that unlike trailers, which inherently want to jackknife under braking, flat towed vehicles want to stay going straight.
Regarding stress on the pinz drivetrain, I routinely drive my pinz at 70 on the interstate if traffic allows for safe following distances. Not a stress issue on the drivetain. Rotational velocity on the hub seals is not an issue, and the overall drivetrain is under less load than you see on a typical trail in 4wd.
All that said, even with a very good trailer, top of the line intertial/proportional Tekonsah brake controller, it's just less tiring/risky to me as a driver to drive a given speed flat towing rather than on the trailer. For any given road/traffic condition, I probably average 10 mph faster flat towing. That's with the Krois designed tow bar that the factory also uses.
Not trying to talk folks into flat towing. And as discussed in detail in this forum, lot's of differing views as to what the state rules are.
But for me, that whole trailer sway thing to me is a far greater risk. I've had it happen trailering the pinz before I got tie down points dialed in, and another time trailering a small backhoe. You may think you have it right, but have a semi pass, or hit a bump, and it changes the dynamics enough that the oscillation starts. Some dampen themselves out. Others, like the mog, get (in engineering terms) positive feedback, and the oscillations increased. The only solution is to accelerate out.
One thing for sure, watching that video made my hair stand on end!!!!
Have fun,
